    Is the mass of a PhyiscsBody/Mass in kg? Apparently until recently in old unity Physics, mass was an arbitrary unit. So if wanted my object to behave correctly for 100lb, would I just convert to kg, giving me ~45 to put into PhysicsBody?

    Just as with classic Unity physics:
    • The units are arbitrary and could be whatever you want (if, for example, your simulation was intended to appear as though it were at a very large or very small scale)
    • With all other defaults for gravity and so on you can treat them as kilograms by default
