Is the international units used in Bullet physics?

Is the international units (meter, Newton, Pa) used in Bullet Physics?

Thank you.

I checked some, and the answer is probably yes.

Yes. I have faced only the problem determining btRotationalLimitMotor::m_MaxMotorForce units. In my experiments the unit is not "Newton * meter". I will be very appreciated if someone explains the meaning and unit of the m_MaxMotorForce variable.

I don't actually know, but my guess is that it may be the impulse equivalent of a torque. In other words, perhaps the unit is "Newton * meter * seconds", where the seconds comes from the timestep (dt).

Thanks. I suppose you are right, accordingly to my experients and http://illumium.org/node/31(in russian, but code is in C++ anyway) this value is really angular momentum.

I would say yes, but 24hr-printer-cartridges.com difficult define them, I'll check
