Question

What do you mean by 1hp

Answer 1

Horsepower (hp) is a unit of measurement of power (the rate at which work is done)
It was originally defined as 550 foot-pounds per second (ft-lb/s).
A power level of 1 hp is approximately equivalent to 746 watt s (W) or 0.746 kilowatt s (kW).
To convert from horsepower to watts, multiply by 746.
