I need this system because ı am working on geometric objects in roblox studio and its too detailed .
I just started writing the code so there may be mistakes.
There is too many variables in this script.
And any of them are finished because ı have to measure them as in centimeters but ı dont know how to,so ı just only finished the formulas. QUESTION ONE Is it possible to measure the objects in the roblox studio in centimeters? QUESTION TWO How can i make it? QUESTION THREE
*If its not possible then, is there any way to make a system which is measures the objects as in centimeters? *

---CIRCLE AND CYLINDER
local CylinderVolume = (2 * PiValue * Radius * 2) * Height
local CircleHeight = Diameter or (Radius / 2)
local ArcLength = (2 * PiValue * Radius) * (CentralAngle / 360)
local CircleSphere = PiValue * (Radius * Radius)
local CirclePerimeter = 2 * PiValue * Radius
---TRIANGLE
local TrianglePerimeter = EdgeA + EdgeB + EdgeC
local TriangleSphere = (SoleLength * TriangleHeight) / 2
---VERTICAL TRIANGLE
local PythagorasEdgeLength = (VerticalEdgeA * VerticalEdgeA) + (VerticalEdgeB * VerticalEdgeB)
---SQUARE
local SquareLenght = EdgeD or EdgeE or EdgeF or EdgeH
local SquareSphere = EdgeX * EdgeY
local SquarePerimeter = EdgeX * 4 or (EdgeD + EdgeE + EdgeF + EdgeH)
local SquareDiagonal = (EdgeX * math.sqrt(2))
---VERTICAL TRIANGULAR PRISM
local LateralSphere = (EdgeU + EdgeI + EdgeO) * TriangleHeight
---PARALLELOGRAM
local ParallelogramSphere = HorizontalEdge * ParallelogramHeight
local ParallelogramPerimeter = (HorizontalEdge * 2) + (CurvedEdge * 2)

Well roblox uses studs. Im not sure if it’s based off of any real value. You can make a custom scale and base all avatars and building off of it. You can use the average size of a adult male(176 cm) to base the size of cars and buildings.

I recommend making functions to convert your ratio(between cm and studs) from studs to cm and cm to studs for design. Look at the trivia(bottom) of this roblox fandom for “official” conversion from studs to cm

I am talking about the short and long edges of the geometric objects. The object we know called Part actually is a rectangular prism and has a short edge (Vertical edge) . and the circles have a Radius and Diameter so how can ı calculate them as in centimeters?

and according to the triangle inequality, the sum of the lengths of the two short sides of the triangles must be longer than the length of the long side.
According to my system, this must match
