Some Useful Equations

V  = I  x R
(volts = amps x resistance)
P  = I  x V
(power (watts) = amps x volts)
746 watts  = 1 Horsepower
Horsepower  =(RPM  x Lbs-Ft ) / 5252
(mechanical Hp)
Newton-meter(Nm) = 0.73756 lb-ft
example:
100 Nm * 0.73756 = 73.756 lb-ft
Kilometers(km) = 0.6215 miles
example:
10km * 0.6215 = 6.215 miles
