I’m pretty sure characters were originally supposed to be the size of Lego figures (due to studs, Welcome to Roblox Building etc). Not sure if this has changed since Roblox has advanced a lot.

if they still are based on size of lego figures then i guess it would be best to size things based off lego’s scaled stuff than real life stuff… but i am guessing roblox has changed it since advancing, but not sure what the official scale is due to no one can agree and i found R6 is lighter than R15 so you also move get to a certain momentum faster if being R15 so it isn’t really built to be any agreeable scale.

There was a blog post made in 2012 stating that
1 meter is equal to 20 Roblox studs

@0xBAADF00D Do we have an official metric? This seems to be all over the place at this point.

It isn’t consistent across different contexts. In VR, 1 meter is 3 studs. But for gravity, 1 meter is 20 studs; that is, if you consider Roblox’s gravity to be consistent with real life; I’m not sure it really is.

Gravity is the only relevant metric, everything else is relative due to the different perspectives.
Some ants for example can run just as fast as a cheetah relative to its bodysize but in absolute terms it is obviously slower.
Gravity on the other hand affects both animals exactly the same but from the perspective of the ant it affects it many times more than the cheetah, and an ant jumping up its body height will reach the ground much sooner than a cheetah jumping up its bodyheight.
Now you jump in the air and compare the time it takes for you to touch the ground again compared to the time the ingame character takes to do just the same and it is pretty much the same deal as with the ant vs the cheetah example except that I don’t think you can jump several times your body height like the default roblox character.
That is why 20 studs = 1 meter assuming that default ingame gravity = earth gravity.
It is of course just as correct to assume that 1 meter = 3 studs in which case we are playing human-sized characters on a planet with 2.6 times the surface gravity of Jupiter.

It really depends on what the units of mass actually are, since inertia is independent of gravity. But I don’t really know the answer to that.

But gravity is independent of mass too (atleast for the object being attracted by it), that is why a feather will fall just as quickly as a stone if we ignore airresistance

Yes, but if you push on an object with the same force, it will always experience the same acceleration regardless of the gravity field it’s in.

Thanks for the replies. So to summarize: If you scale from human-sized buildings to Roblox size. The measurements would be 1 meter = 3 studs. Although in accordance from a Roblox blog post: Gravity in roblox is 196.2 studs/s^2 (print(workspace.Gravity)
Gravity on earth is ~9.81 meters/s^2
(196.2stud/s^2) / (9.81 * meter/s^2) = 20stud/meter

I know this is a very late response to this topic and that there is already a solution but I wanted to share what the walkspeed was if I were to walk 16 walkspeed. So what I did was measure out a length, which was 102.05 studs, and then set a timer and walked to a brick which stopped my timer. So the calculation here is, if you have 20 studs per meter, 102.05/20 which would equal 5.1025 meters. If you are passed freshmen year of physics class you would know that if you take the distance divided by the time you would find the speed of an object. So the time I got was 6.6 exactly and so I did 5.1025/6.6 which gave me .77310606 m/s.
So if you were to try and find the speed of a character, you take the distance divided by the time. In my results, I found that the walkspeed of a character in meters was approx. .77 m/s.

Are you sure the workspace gravity should be 32.2? i tried it and it seems to be like you are walking on the moon.

I think he meant 332, not 33.2

32.2 studs/s^2 is technically correct if for 1 stud = 1 foot, but you have to adjust Humanoid.JumpPower accordingly, to ~8.2, but I still don’t think this ends up looking too good so I usually leave gravity as is. I think the very high default elasticity of collisions has a lot of do with how it looks. Also, falling things look slower when there is no motion blur or when you’re zoomed out with little sense of scale.

Correct, everything is relative, if you used to high jump power and high gravity, obviously moving to a lower gravity is going to seem moon like. However yes 32.2 is correct. You have to adjust jump power and other physics objects if you didn’t design around a gravity of 32.2.

I think there’s finally a canon answer. With the release of World Panel Settings, 1 stud is exactly 0.28 meters (14/50 = 0.28). That’s ~0.92 feet in imperial units. I’m guessing this scale was made with RThro proportions in mind. A door would be roughly ~7.24 studs high and ~3.26 studs wide (assuming that the average door is 6’8" tall and 3’ wide.)
(average door size vs RThro character pictured here)
This contradicts what they said in a blog post years ago, though, where “one real-world meter is 20 studs”.

This is really cool to look at, but I have one question, how did you get .28 for 50/14, it should equal ~3.6
studs/meters = 50/14
For every stud, there is .28 meters and for every meter there is ~3.6 studs, just saying you may of gotten your math mixed up and it just didn’t make sense to me.

Typo, that should be 14/50

So I was just trying to implement the most realistic gravity possible, and it turns out 1 stud is EXACTLY .92 feet according to the physics.
I didn’t realize this, but when converting “realistic gravity” (9.8m/s) (35/s/s) to real realistic gravity (based on the .92 number), I found that – based on Roblox’s “20 studs in 1 meter” – measurement, 20 studs = 3.28084 feet. If a stud is actually ~.92 feet, then 20 studs should actually equal 18.4 feet. That is 5.608 times the 3.28084 value stated earlier. That means that actually realistic gravity should be 5.608 times Roblox’s 35 stud/s/s “realistic” gravity. That number?
It’s 196.28 studs/s/s… AKA “Classic” gravity.
So yes, I would say that .92 is both proportionately and physically proven based on those numbers. Who knew Roblox Classic physics were based on .92 feet per stud? Kinda interesting I think, I just stumbled across it.

By 36 studs do you mean 3.2 studs? Sorry for bumping this but, I think that’s another typo.
