Power converter

Convert power

From

Power units covered here: watts (W), kilowatts (kW), milliwatts (mW), horsepower (mechanical) (hp), metric horsepower (ps) (PS), megawatts (MW). Power = torque × angular speed, so it pairs with the torque and rotational speed converters. Pick a pair below for its formula and worked factors, or open the full power converter.
