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

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 |
