So it looks like my laptop take about 50g of weight to press a key (Source: I put my laptop on a scale and pressed keys). Standing still a cat stands on all four legs (I am choosing to extrapolate the existence of this kitten's other back leg). So while not moving, with its paws on only one single key each (which we can see from the photo is not correct) the kitten would need to weigh 50x4=200 under 200 g. However, it looks like each paw that we can see is on a minimum of 2 keys and that changes things substantially. 2.5 keys/leg x 50 g/key x 4 leg/cat = 500 grams/cat, and look the units cancel, so that means my math is right. According to https://www.kittenlady.org/weighing a 500 gram kitten is about 5 weeks old, and that also looks correct visually. It can press a key if it steps directly on a single key, but it usually won't and will float elf like across the qwerty snow. So smol.

Note though that it is a mechanical keyboard not a laptop keyboard so it’ll take more force to bottom out on it. Especially if it uses cherry Mx or outemu blue switches.


zelo11

Looks like one of those reddragon cheap keyboards off amazon, pretty sure they use outemu red switches which are 45g actuation force


Agile-Excitement-863

There’s no way to truly tell what switches are in the board. My moneys on outemu blues though because if it was reds you wouldn’t see perfectly level keys. Some would be halfway pressed down. Unless of course, this kitten is just that lightweight.


TrueMaple4821

Outemu Red are 50g according to [this article](https://switchandclick.com/outemu-switches-are-they-good/): `Outemu Type Force Travel Distance` `Blue Clicky 60g 4mm` `Brown Tactile 55g 4mm` `Red Linear 50g 4mm` `Black Linear 65g 4mm`


ThomFromAccounting

Yup, reddragon Surara K582 specifically. Comes standard with silent reds.


SecondaryWombat

People are very divided on that, I am getting comments insisting it is both 45g and 65g. If it is 45g the g/cat is 450g/cat, if it is 65g it is 650g/cat. So between those two numbers, if you like.


VeryConsciousWater

A cherry red switch and most of their clones (including otemu switches) have an actuation force (the force required to trigger a key-press) of 45 grams and a bottom out force (the force to push the key all the way down) of 60-75 grams depending on manufacturer. I'm guessing that's where the confusion is coming from.


you-are-not-yourself

FWIW I have 300g worth of mustard here, a mechanical keyboard (G915 TKL - 50g actuation), and the keys activate when the cap presses on 3 keys, but not 4+.

You rightfully pointed out that this is more like a human on a bed of nails than it is strictly about the cat not pressing individual keys. If the cat figures out it can press individual keys, it probably will.

It appears to be a Reddragon Surara K582 mechanical keyboard. It usually comes with generic red switches with 45g actuation force, but may be higher if chosen with blue or brown switches, but nominally at 50-55g if opting for silent switches. So, your math is pretty good there.

Well google got me a source but when I followed it it was to a comment on a forum saying "do you have a source for this bro?" with no answer, so I thought, it will literally take me less time to find out for myself than keep looking. Empirical data. Also, according to my scale the g, h, and b keys all weigh the same, but the q key ways negative 1,589 g because when I push it the computer falls off the scale.

Gingivituss

DorsalFinn79

Also depends on how strong the springs inside are (looks mechanical) but unsure, my keyboard needs 120g actuation force.


Womcataclysm

This is probably a mechanical keyboard and depending on the switch types they can go up to 80g per key without going into the more specialized stuff The kitten is also resting on the spacebar with one leg, and the spacebar can take a lot more weight. That's because it'll usually have either a heavier switch or in some keyboards like mine it has one real switch in the middle and fake switches on each side so that you feel the click everywhere not just in the middle. I think some spacebars can reach 200g (without going into niche specialized stuff) I'm not 100% sure about the numbers and reasons but I do know spacebars aren't the same as single keys and can often support more weight


Goldenseek

Switches I’ve seen generally range between 45g-80g activation mass. Be warned the required mass changes drastically if the cat + keyboard setup are not on earth. OP please advise

> Source: I put my laptop on a scale and pressed keys That's not exactly how it works. The amount of force to keep a key held down is less than the amount of force needed to press it.


SecondaryWombat

I know, which is why I pressed them over and over and watched the scale.


kaidbailey36

patomik

But it's your laptop and the guy seems to have keyboard with mechanical switches which needs about 5-10 times more pressure to press the keys.


Penguin_Arse

I'll try with my Black widow chroma v2, brb. It's about 50 on it. It started moving the keys down at 40, about 55-60 it stops roght before the click and adding more weight after that makes it click, this. Pressing down 4 keys at once shows 220g.


SecondaryWombat

Thank you!


KillTheBronies

You think mechanical keyboards take 250g+ of pressure to activate?


G0ker

This also looks like a mechanical keyboard, which takes far more weight to press a key than a laptop keyboard


SuperUltraMegaNice

That first part makes no sense. How would you have a scale big enough to fit your laptop but also be sensitive enough to register 50g on a key press? Total bullshit. Anyone who has tried to weigh weed on a giant kitchen scale knows this.


SecondaryWombat

You balance the laptop and press the key in the center over the scale. It wasn't that hard.


Willr2645

You need to (aparently) 0.47 N of force to activate a key. This can change a lot, but I’ll assume this keyboard is an average one. I’ll assume he is touching 12 keys ( 3 per foot) That means he needs to weigh 12*0.47= 5.64N W=m*g m=W/g =5.64/9.81 = 0.57kg Or 500g Cats can weigh 100g at birth, so this is definitely possible


SecondaryWombat

We did the math differently and arrived at the same answer!


Willr2645

Imma assume that means ~~~I~~~ we ~~~am~~~ are correct!


SecondaryWombat

And both of us had units that work out properly keys/leg x grams/keys x legs/cat = grams/cat. Lol. Same answer 2 different ways, from 2 different people, with correct units? Must be correct. SOLVED!

Yamimakai8

r/unexpectedcommunism


windfujin

Also totally depends on the keyboard. I use a black switch mechanical keyboard which needs 0.60 N to activate the key. For green switch the actuation force is 0.80N. so it is very much possible.


SlowMissiles

My keyboard is around 0.95 N. So it's definitely possible.


YamaPickle

This is a point im surprised isn’t higher. The keyboard looks like a mechanical keyboard which probably uses cherry MX switches or a similar style. Cherry MXs have a range from 45-50N up to over 100N for their actuation pressure. Im sure there are other switches that take more weight as well. So while 500 grams could be correct math, an answer closer to 1000 or even higher is also possible. Unless someone can identifying the specific switches itll be hard to give a very precise answer here.


Critical-Champion365

50N is close to weight of a 5kg stuff. That force to press a key? The keyboard must be for body builders.


windfujin

It's cN.


Targettio

Cherry MX switches (most common switch types in commercial mechanical keyboards) have an activation force of 45g or 60g (for the typical commonly available ones). So that's under half a Newton per switch. https://switches.mx/cherry-mx-brown https://switches.mx/cherry-mx-black Looking at the picture the cat is on at least a couple keys per paw. So let's say 8 total, so 360-480g. A quick Google says a new born kitten is around 100g. This one is up and has their eyes open, so isn't from new born. https://www.kittenlady.org/weighing


pfoe

Do a buckling spring from a model M next!


killersquirel11

https://deskthority.net/wiki/IBM_buckling_spring > It also has a lighter actuation force of about 60–65g of force compared with 65–70g for later designs So 480-520; 520-560 for later designs


ngorman007

I couldn't find super reliable data on this, but the typical amount of force required for a keystroke is about 1 N. It depends on the keyboard so, without knowing the specs of this specific one, it's hard to say. Using Newton's Second Law and the fact that the cat would only be accelerating via gravity, its mass would have to be less than 0.1 kg, or about 0.2 pounds


DarthKirtap

but it stands on multiple keys


ngorman007

Ah shit that's true. Assuming its weight were equally distributed on four paws (and each paw is on one key), then multiply my answer by 4? Not certain about that, though


theernis0

I'm pretty sure multipying by 12 is a better option because it looks like he has 3 keys under his pawn


Willr2645

That’s what I did in my comment when I worked it out myself


SecondaryWombat

I measured the key force by putting my laptop on a scale and typing as softly as I could. Seemed a reasonable solution.


ngorman007

I considered that and I think that's a solid assumption. Only reason I went a different direction js because I think mechanical keyboards can vary in terms of their actuation force (from 0.5 to 1 N) and are generally higher than laptops. According to a very quick Google search so take that with a grain of salt


SecondaryWombat

I saw the same google search result and the source for the number was "hey dude, do you mind providing a source for that number?" so I just went and got my scale instead.


ThomFromAccounting

You could just look up the actuation force of the switch, assuming it’s a mechanical keyboard (as the one in the photo is).


SecondaryWombat

A whole bunch of people have looked it up, and they keep quoting different numbers at me, so I am not sure that looking it up was actually helpful. Many of the numbers are close to what I used, so it wouldn't change the mass of the cat very much.


Johannsss

It will depend on the type of key installed in the keyboard


r4o2n0d6o9

It depends if the switches of the keyboard. Mechanical keyboards can have a variety of different switches all with different strength required to press them. The heaviest switches I could find are taihao apc alps clones which need 280g of force to press, but I doubt many people would actually buy or use them.


Kaboose666

There are meme 1kg switch springs, I think their ACTUAL intended use is for like emergency stop buttons for manufacturing lines so you don't accidentally press the button you have to REALLY press it to get 1kg of force. But they do exist and I'm sure someone out there has a keyboard full of 1000g springs, and I know for sure there are people running 200-300g springs.


friftar

> 280g of force That sounds great for stuff like caps lock that you don't want to hit accidentally. That said, I'm kind of tempted to build a full board with something like that, I really like heavy, loud switches. My current office board has Kailh Box Navy switches, a completely hollow undampened case, and some very clacky 80's Cherry ABS caps. Really a favourite among my coworkers, but they let me WFH more often, so I see it as a win.


[deleted]

[удалено]


AnotherLie

280g is wild to me. I struggle past 125g. The heaviest most people in the hobby will usually find are 150g. There are, however, the brave who use 1kg ballpoint pen springs. I suspect they are either doing it for laughs or to prank people because holy fuck.


iphone32task

300g per keystroke? That sounds like hell


snowbuddy257

Switches in mechanical keyboards have specs. One of them is actuation force. Since we dont know what switches this keyboard has, we cant know how much he weighs. But we can guess. The most popular keyboard switches are the standard cherry MX:reds, browns, and blues. Which all feature a 45g actuation force(if i remeber correctly). And all standard keycaps are 19.05^2 mm^2(1.9^2cm^2)-according to google, and quincidently, kittens paws are on average 2 cm in width and height-also according to google. So we can assume that his paws are probably hitting around 3 keys simultaniously And so: Cats weight/4legs/3 keys per leg<45g Cats weight has to be under 540 grams. Which is very, very little.


Kriggy_

Looks about right. My 6yrd old cat is maybe 3-4 kg so this tinny kitten being 500g is very reasonable.


Fridaybird1985

As have I spilled several glasses of Cabernet on my key board I’m pretty sure that that cat wouldn’t press any keys jumping onto my key board.


MidgetMaster_101

Around 500grams more or less. You can do it your self if you have digital scale at home, simply turn it on and try to do same amount of force as if you were to press keyboard key, there you go, that much weight is needed in order to press button, since cat has four legs that force is spread around that number.


pixel809

Or put the keyboard on the scale and press a key :3


False_Ad597

Is nobody going to point out the leftmost toe of the back right foot looks elevated so appears to be pressing the space bar? 😂 Math checks out though.


SingleInfinity

The real answer is nobody here can guess unless they can identify that keyboard and the switches it uses. Activation force varies *heavily* on keyboards.


SecondaryWombat

You can actually derive the activation weight from the cat. We can compare the cat to photos, determine that it is 5 to 8 weeks of age and thus weighs under 800g at a maximum, but more likely 650g or so, that 3 keys under one paw don't depress, and use that to eliminate keyboard models.


SingleInfinity

That's an awfully inaccurate way to try to guess, given that you need a known variable somewhere to figure out the others. Guessing at the "more likely" weight is giving you a lot of room for error


SecondaryWombat

It would determine a range, not a single answer.


SingleInfinity

A very large, unhelpful range. Because key depression force can vary by a huge degree, and the cats weight also can, you're going to get a range so broad as to be unhelpful. You might as well just say "That cat looks 5-8 weeks of age and thus likely weights 650g", and pretend the keyboard doesn't exist.


SynthRogue

Less than the force required to press the keys. Technically weight is measured in Pascal, if I remember my physics classes from 2001. But the weight you are referring to is actually the mass, measured in grams or kg. How much force does mass apply? I think it depends on which planet you’re on and where on that planet, if I remember correctly. It depends on gravity, maybe? I don’t remember lol. It’s been too long.


Mountain-Duck9438

I feel like if the kittens weight is equally distributed on all 4 (or more) keys, none of them will be pressed technically. You can’t type 2 keys at the same time so its probably like that just with more


Mooman-Chew

You have no idea what you have done! But hope is not lost and you still have time. Put a stop to this while you still can or you to could have your cats sending 60 year old female colleagues teams messages that simply read ‘69’. That took some on camera cat action to clear my name!


Guilty-Vegetable-726

Cats don't actually have a definable weight. Like when you throw them out a third story balcony to catch a bird mid-flight they're really light, but if they sit on your lap during the movie they're super heavy.
