What is the unit of measure of radius in the sphere?

I’m trying to increase the radius of a sphere in ue4 but I don’t know if the unit of measure is in cm, km or is the same thing as Unreal =cm

Same, all distance measurements are all the same, it common in all programming as it would have been annoying and waste of performance to operate in 2 different distance units

But whatever it is cm it’s debatable as as in float based vector graphics distance can be scaled to any unit, you can decide that 1 distance unit in UE4 is inch and it will work out fine. Only limitation is float precision, the bigger integers in float or smaller fraction the less precise it becomes.

thanks____
