From what I am seeing, the force for VectorForce uses a Vector3 which is in studs (length), but in real life, forces would be expressed as kgms^-2, (length, mass and time). Does anyone know does the vector3 of force convert to real life units (kg, m, s)?

I need to know the opposite of this, newtons to Roblox force or kilograms to Roblox force, here’s a sample of a script I made if it helps:
local w = script.Parent – the wing
local f = Instance.new(“BodyForce”, w)
local P = 1.17e+0 – densifty of air
local Cl = 1 – lift coefficient
local V = w.Velocity.Magnitude * 5 / 100 – velocity in meters/second
local A = 2 * (w.Size.Z * w.Size.X + w.Size.Z * w.Size.Y + w.Size.X * w.Size.Y) * 5 / 10000 – surface area in meters^2
local L = Cl * A * 0.5 * P * V^2 – lift in newtons
local Lk = L / 9.81 – lift in kilograms
print(L)
necro bumping here but what the hell are those variables?
This thread explains it a whole lot better and uses Roblox’s new physics to get realistic data. My assumption was that 20 studs was equal to a meter.
