Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I'm working on a generalized model for motor / gear systems in SPICE and came across something I don't understand:

Given that the inertia, J, is in kg m^2

and my base unit for angular velocity, w, is kRPM

and the basic equation for energy is E = 1/2 J * w^2

How or what is the conversion factor such that I get joules as my unit of energy?

I feel really silly on this one, I can only claim memory loss...

Thanks in advance,

Mike
