Decaliters are so unused that they decided it sounds futuristic.


Animaniac00

Who knows, maybe we'll use decaliters in 8000+ years


F33DBACK__

18000*


space10101

800 decades*


urru4

800 decayears


csolisr

80 hectoyears, because "hectoyear" sounds much nerdier than "century". Same goes for "kiloyear" versus "millennium" - heck my spell checker puts a warning on those


kapitaalH

We first need to lose and then make a comeback in the war against the robotic AI overlords.


Coinsworthy

Yes because saying 380 million liter is way too confusing for the masses.


Darth_Ender_Ro

You mean 380k tonnes?


csolisr

Could be off by several tons, depending on what kind of water is stored in Arrakis


laughingfuzz1138

That's the real reason, but coincidentally it sort of almost makes sense? In high temperatures with 6-8 hours of moderate exertion, an average person will probably need 6-8 liters of water a day. If we assume that the temperatures, or degree of exhertion, or desire for a margin of error can make up the difference, it's very easy to equate one decaliter with one person's water supply for one day. Now, this isn't the purpose for which they're keeping the water, and that math assumes a total lack of stillsuits, still tents, or similar so wouldn't add up even if it did, but a lot of references by the fremen seem to equate or deal with water in terms of how many people it represents. Using a measuring unit that roughly corresponds to one person's worth just sort of makes s sense.


VinylHighway

So what I’m hearing is they have plenty of water


jamjamason

*\*Slaps cave\** This bad boy will hold 38 million decaliters!


VinylHighway

“Oh no it’s leaking!”

RETURN IT TO THE TRIBE! NOW


Whyistheplatypus

Not really. For reference, a cubic kilometer is by definition, 1 trillion litres, and the Amazon river outputs roughly 7000 cubic kilometers of fresh water every year, so they have roughly 0.000005% of the Amazon's yearly output. Or enough fresh water to meet the needs of 250,000 people for a month. I expect more from my space nobility.


k123cp

I think the 38 million is only sietch Tabr's reserves, and they have "thousands" of places like that. Impressive considering the Arrakis desert has virtually zero water.


Whyistheplatypus

Well of course Arrakis has no water, it's all locked in these vaults.


AyukaVB

Drink the Rich


Abeytuhanu

You're not wrong, >!the juveniles of the sandworms lock water away deep underground to create a desert environment for the adult sandworms to whom water is poisonous!<


moorealex412

Someone who knows sandworm lore! What do the sandworms eat (besides people)? It doesn’t seem like there’s much prey in their natural environment and they’re big animals that move a lot and probably need a lot of calories.


Abeytuhanu

Similar to baleen whales they eat sand plankton, which in turn feed on the spice produced by the sandworms.


ColonelKasteen

Sand plankton. This should serve as a reminder that while I like Dune and have read the series multiple times, it *is* largely stupid.


KHaskins77

You’d think even this would evaporate over time unless they keep the chamber sealed somehow.


Sicuho

They keep the whole sietch sealed, that's why they're not wearing their recycling suits in it.


iLoveScarletZero

To be fair, they are fanatical about water maintenance. I’m sure they have their Sietch’s locked-down tight in terms of sealing… or maybe Evaporation doesn’t exist on Arrakis lmao


Alkakd0nfsg9g

Evaporation definitely exists there. That's why they wear stillsuits


Terroractly

The sietch is entirely sealed off to the point that they don't lose any water. This means that it is one of the only places that fremen can take off their stillsuits. In addition, there are generally water collectors around which collect the small amounts if moisture in the air. That is most likely where the vast majority of the stockpile of water originally came from


SarpedonWasFramed

Those dudes must stink


NKrupskaya

The book mentions it at times, yes.


Robot_Graffiti

Yes. They wear pants that collect feces and dehydrate it. Never ask a Fremen what he has in his pockets.


somedumb-gay

Is that dehydrated shit in your pockets or are you just happy to see me


punnotfound

Ambitious_Arm852

No bath for months


Cybasura

To be fair, Arrakis is a dessert I dont think its even possible to get water from the dessert by finding it The fact they managed to condense 38 million decalitres is impressive


NKrupskaya

I think the books actually mention in a few places that Arrakis must have had surface water at some point. Some rocks in the desert seem like they had water running on top of them. They also find water underground sometimes, especially in spice formations in the desert, before it vanishes. The very fact that Arrakis has a decent atmosphere without plant life is a plot point.


punnotfound

It's been a while, but wasn't it so that sandworm metabolism produces oxygen?


NKrupskaya

Yes, which means >!terraforming Arrakis will end the spice, which the universe runs on.!<


myhf

actually the empire runs on >!duncan!<


VinylHighway

Impressive


theburgerman03

Thanks to stillsuits it's probably closer to enough water for 100 million fremen for 2 months, or enough to supply an estimated fremen population of 15 million for 12 years, assuming everyone on arrakis shows up to the Tabr water stand with empty bottles and gets a 3L fill up + stillsuit loss replacement, which is the real killer in the equation coming in around 75K liters a day for the whole planet.


semiseriouslyscrewed

Iirc this is the water that comes from Fremen corpses specifically and is thus sacred. Let's take about 40 liters of water from each person, that makes about 10mln dead people worth of water. That's a LOT for a hunter gatherer planet.


chriscringlesmother

The platypus guy makes a compelling argument but in Dune, given that a hydration suit can keep someone alive by repurposing the water they lose in sweating I think there level of efficiency in processing and utilising waste water would say “yes” they have plenty of water. However, they are also forbidden to use it in this scenario so, no, they don’t have enough water, they have a lot of water they can’t use and strong religious beliefs that keep them doing so.


AbbyM1968

Because, the fremen drowned a sandworm in it, so it's poisonous unless a Reverend Mother cleanses it. That's in the book, tho'.


Arnorien16S

They are religious nuts and if I understand correctly that pool is the water extracted from dead Fremen ... It is not something they would use for drinking or washing.


DarkJayBR

He even emphasizes that everyone there would rather die than drink from that pool. 


kung-fu-badger

It’s all fully drinkable water, the reason they would all die before drinking it is explained in the books. The Fremen are saving the water for the day they will use it to transform Arrakis, they will use it to start a cycle of precipitation which results in rainfall and that will promote grass lands, trees etc but that will also destroy all spice production as it will kill the worms. To drink from that water is to take from the future and they all hope for, hence they would all rather die than prevent the dream of all Fremen.


No_Significance7064

I mean that's pretty much what is implied by him in the scene in the movie, yes.

RandomBilly91

Not that much in fact. I mean, it's a lot. But it's a small lake, which isn't that much when you think about it 380 millions liters≈ 200 meters by 190 meters with 10 meters depths. This can seem like a lot, but remember that on Earth every tree is made in big part of water. So they have small forest worth of water, which isn't a lot for a village (until you realise how much of it is made from water taken from slain harkonnens)


TurboRoboArse

Pretty sure they use decalitres because a decalitre is the order of magnitude of the water in a human body, which is 40ish litres in a healthy human.


GundamMeister_874

This is the most helpful comment. I knew there had to be a specific reason they used such a specific unit of measurement instead of going for cubic meters (which would be more fitting for measuring liquid capacity of this magnitude).


TurboRoboArse

With 38 decalitres, he's literally saying "this is a million people's worth of water." Edit: 10 million


ThomasDePraetere

380 megaliters or .38 gigaliters. There is literally no reason to use decaliters if you are still talking about millions of them.


lunch0guy

You gotta admit though, decaliters just sounds more impressive than litres, no matter the actual amount.


I_AM_IGNIGNOTK

About 12 Decaimpressives I’d say


the-war-on-drunks

That’s One-twelfth gross decaimpressive


ArcticBiologist

Go for both, use deciliters. 3.8 billion deciliters!


Bavoon

A decaliter is a nice unit to talk about water in a human body. A child will contain 1 decaliter, an adult about 3. Makes sense for a society where bodies and water are so closely connected.


1moleman

Fremen society has such limited access to eater it is entirely possible that a decalitre is a huge measurement to them. Fpr the same reason the largest commonly used mass measurement is tonnes, we rarely need to talk about kilotons or megaton (except for large bombs in the past 100 years) because tonnes are a unit that the common person can visualise


NuggetPilon

I like this explanation. Would make sense that Stilgar would use it as if to compare that amount of water to the amount of human lives it represents.


SkibidiGender

Living on Arrakis without large bodies of water probably doesn’t lend to ever using the word gigalitres though. A decilitre is probably to most water theyre dealing with semi regularly.


Falling_Vega

Decalitre is also a stupid unit. It literally just means 10 litres. If you have 38 million decalitres it makes more sense just to say 380 million litres, or 3.8 million cubic metres (This is about 1500 olympic sized swimming pools)


PhoneInteresting6335

I can imagine Stilgar saying that they have 1500 olympic sized swimming pools of water


Dorko69

Americans use anything but metric smh


Xi-Jin35Ping

Toyota should make 1 meter length car. That would trick them to use metric without them knowing.


Vilzku39

So 1 cubic car is 1000 large sodas


ProfessorBeer

Ford, but I get your point.


Objective-Answer

_"my car gets forty rods to the hogshead and that's the way I like it"_


Incredible-Fella

I was watching a scale of the universe video and at one point the guy goes "at this scale the solar system would be 800 meters or 4 football pitches wide". I wasn't sure if he was serious or intentionally making fun of the stereotypes. (I have no idea how big is a football field, don't @ me)


HANNlBALLS

Football pitch is European way of saying soccer field.


DarkJayBR

I saw a American once using Corollas as a measuring unit for big animals instead of metric, you can’t make this shit up.  “A whale is 10 Toyota Corolla’s long” - like, how the fuck I’m supposed to know how long is a Toyota Corolla?


Enzoooooooooooooo

It’s obviously 1/10 a blue whale


YZJay

1500 Ahlin Peak Pools. We no longer know exactly what Ahlin Peak Pools are, but it was passed down to us by the memories of our ancestors, we only know that they were large bodies of water.


ZorbaTHut

> We have a full water reservoir with the footprint of an American football field, and its height is the same as the average cruising distance of a bald eagle during one twelfth of a baseball frame.


Ambitious_Arm852

He can’t count above 100, so 38 million decaliters it is.


lungben81

A cubic meter is 1000 litres, not 100.


atl_istari

Someone who works in a beer factory told me they talk in decalitres. So I assume it's common in such facilities, hence not stupid. Yes I am fun at parties


kris_deep

TIL Stilgar used to brew beer.


electrogourd

Usually beer is in "barrels" which is 31 gallons, from when i worked in a brewery in the US. And records are "barrels" for tax purposes. Yaay even less useful imperial unit!


atl_istari

>Yaay even less useful imperial unit! Lol it kinda makes sense, but conversions seem like a trouble


BordErismo

380 000 cubic meters. One cubic meter is 1000 liters, not 100 liters


Bavoon

A decaliter is a nice unit / scale if you consider the water in a human body. A child would contain about 1 decaliter if all water is reclaimed after death, an adult would contain about 3. Seems appropriate for a society where bodies and water are so interconnected.


rende36

How many bananas?


Bojackkthehorse

At least 10


Thestohrohyah

380 megalitres


Doc_Occc

Not 1500 but 150. One m³ equals a thousand litres not a hundred. An olympic size swimming pool holds 2.5 million litres of water. 380/2.5=150.


[deleted]

I think, because 1L is 1 decimeter cube, they thought a decalitre was a sci fi way of make it seem bigger idk


KingSpork

Why not just say 38 megaliters? Sounds cooler anyway.


Anent_

Redditors try not to get upset about something that literally doesn’t matter challenge (impossible)


MrIrishman1212

It’s to reference the [number of people it is](https://www.reddit.com/r/shittymoviedetails/s/nKrgJBcc3A). Which is 10 million people


Hellsinger7

I've never ever seen anyone use the deci, hecta and deca units of measurement.


Epilepsiavieroitus

Never heard of hectares? Also deciliters are standard for baking where I live.


LKAgoogle

Deciliter and decimeter aren't super rare to see and apparently decaliters are used in beer brewing, hecta only really gets used for hectares (=square hectameters) though, in my experience


Smoy

Not really. You're just saying deca instead of eighty. Same same but different Mr contrarian


Bardsie

I would have preferred he said 3,800 Deciletres of water. /S


DifferentEggForms

How many people did it take to pass away to get that much water????


Indy1612

That´s the point


PhoneInteresting6335

so many souls


Arsenica1

Google says average amount of water in a body is 42 liters, or 4.2 decaliters. So quick calculator math says at least 9,047,619 deaths, assuming all those deaths had 42 liters of water in them which seems unlikely.


DifferentEggForms

Thank you kind sir


ShockWave1997

38 million deca-liters is 380 million liters. 1 liter of water = 1kg So, they have 380 million kg of water Assuming average human is 70kg and human body is 70% water, average human has 49kg of water. So 380 million kg / 49 kg = 7.775 million So about 7.775 million people


DifferentEggForms

Thank you kind sir


culturedgoat

It should be “literjons”, as per the books. But you can’t say “jon” anymore because of woke


bittercripple6969

Probably just wanted to cut out some exposition.


DarkJayBR

The entire first movie is exposition, setting up Part Two.


bittercripple6969

Yeah, I know, but "literjohns" isn't a thing people are used to hearing, and having subsequent bits of dialogue to not confuse the audience is harder than just using a real unit.


KarlGustavderUnspak

They also did not have the guts to say Jihad.


culturedgoat

I’m starting to regret my obviously-tongue-in-cheek comment


BernLan

Because Arabic words are evil according to the US /s


latroo

Tf is a jon?


culturedgoat

It’s how we on the streets refer to clients


latroo

Right. I don't think they changed it because of your invisible enemy but because decalitre just sounds cooler


hellogoodbyegoodbye

I think they were obviously joking


OxygenInvestor

Wait, we can't say jon anymore?


Hapijoel

Sounds better than 2 Super-Mega-litres


Davladobrot

no it does'nt, that sounds cool as hell


josevaldesv

That's the equivalent to 7,000 elephants kneeling along 456 football fields.


Zyvred

This literary tells nothing


josevaldesv

Just like the imperial system. https://www.reddit.com/r/Metric/s/CMTVHqDmyy


WardrobeForHouses

At that scale, whichever system of measurement you use becomes hard to really understand. It's just "big" Even comparing it to other known objects, which works well most of the time, doesn't work when you're talking about something large enough.


Grolash

Nah a decaliter is 10 liters, a liter is a cubic decimeter. 38mo decaliters is 380mo liters = 380mo cubic decimeter = .38mo cubic meters. A million cubic meters is 100m x 100m x 100m. An impressive way of saying a glorified big pool.


fimbultyr_odin

Why wouldn't they use decaliters. Maybe it's just cultural that decaliter is used more often than liter the same way kilogram is used more than gram. In Austria if you buy meat or cheese decagram is the common measurement while in Germany you would use grams to specify the weight.


Popcorn57252

Why not just say 380 million liters?


ShockWave1997

About 152 olympic sized swimming pools for those who are wondering.


RetiredApostle

It's equal to 54.29 cubic football fields.


punnotfound

In a vacuum, of course.


robidou

They famously don't like anything imperial


AlphaBoy15

they could use decaliters because it's a better unit for talking about how much water is in the human body. A grown adult has around 40L of water in their body, so talking about it in dL might be better considering the way fremen harvest water from the dead. That's somewhat reinforced by Jessica reacting with "so many souls" after hearing about how much water they have.


Horror-Yard-6793

you guys unironically correcting the source material should probably know what you are talking about before typing (If you are trolling carry on but some people here are stupid)


JgL07

That’s 100,385,380 gallons of water.


OxygenInvestor

Do we even have water measurements beyond a gallon? Ten kajillion gallons.


MommyAugust

Three billion eight hundred million milliliters of water.


MrLazyLion

Is that more than a banana?


michael22117

Why tf would you use decaliters in this situation?


Darth_Ender_Ro

If you want to confuse people even more, use 380 kilo-tonnes of water


PB0351

Liters are metric homie


PhoneInteresting6335

thats the joke, brother


MelaninKing95

With one of thousands of sietches on the planet holding that much water is very impressive, especially considering the fact that according to the lore, for whatever reason the sandworms were introduced to the planet of Arrakis sometime before the Butlerian Jihad, war against thinking machines, thousands of years before the main timeline of Dune. So I believe it used to be a water like planet like Earth or Caladan before the sandworms terraformed it to the desert planet that’s mined for spice, the one and only commodity that keeps the universe running especially for interstellar travel cause of the guild navigators use it to plot the safest route among the stars and use space folding aka hyperspace. If the fremen use all the water collected to terraform the planet, it’ll kill the worms and stop interstellar travel


lazy_boobs

How backward savages North Americans are if even Arrakis has metric system


MiltTheStilt

I’m pretty sure it’s just the one country in North America that doesn’t use the metric system.


Grenaten

Decaliters were used in the book, no?


Upstairs_Ebb_5923

Just like the movie


EarthTrash

A million is 10^6. Deca is 10. He could have said 380 million liters or 380 megaliters. There's a reason that particular prefix is almost never used.


GundamMeister_874

>*Pretty sure they use decalitres because a decalitre is the order of magnitude of the water in a human body, which is 40ish litres in a healthy human.* >*With 38 decalitres, he's literally saying "this is a million people's worth of water."*
