I just remember that 1hp is 754 watts, but lets just call it 750. Another magic conversion that I remember from working on that stuff is that Nm * RPM / 9549 = kW. We never used ft-lbs though.
- FooBarBizBazz 5y agokW*h is the unit that absolutely kills me. Especially because people will just say "kW". And before long they're talking about "kW*h per day"... Kills me. "What do you people have against James Prescott Joule?!"
