I was following this tutorial to add conveyors to the env, and was able to create the scene. But I was not able to determine the units of velocity. Are the units as m/s, cm/s, feet/sec. Or are there standard units across all settings?
So for a velocity its distance/second, where distance is determined from metersPerUnit setting of your stage. So based on what your scene is modeled in - cm/m the velocity is in these units.
For angular velocity, all angular properties are defined in degree:
