Why We May Need to kW to Hp Converter

Both kilowatts (kW) and horsepower (hp) are two common units of measuring power. Kilowatt is an SI unit which is used mainly for various scientific calculations and to express the value of power generated by any sort of engine or motor in our daily life. Horsepower is an old type unit of power which is currently used in Europe only as a supplementary one. Therefore, sometimes we may need to use kW to hp convertor to have better understanding in the amount of power generated by any sort of machinery.

For example, you are interested in buying a European car, but in brochures the power of its engine is given only kilowatts. That’s when our kW to hp convertor will come in handy. Or, you bought a water pomp to fill up you water tank and the power of the motor is expressed in kilowatts. Knowing the hp value may help you have a better understanding of how soon your water tank will be filled up.

Definitions:
1 ft = 0.3048 m
1 lb = 0.453592376 kg
g = 9.80665 m/s2
1 W = 1 J/s = 1 N·m/s = 1 (kg·m/s2) (m/s)

Kilowatts to Horsepower Calculation

1 W = 1 J/s = 1 N·m/s  = 1 (kg·m / s2) (m/s)
1 Watt = 1 Joule per second
1 Watt = 1 Newton meter per second
1 Kilowatt = 1,000 Watts

by definition
1 hp = 550 ft·lbf/s // ft: feet, lb: punds, s: second
1 ft = 0.3048 m
1 lb = 0.453592376 kg

so 1 hp becomes
1 hp = 550 x 0.3048 x 0.453592376 m·kgf/s
1 hp = 76.04022591264 kgf·m/s
applying gravity constant
1 hp = 745.699872 N·m/s

we need to find the 1 newton per second
1 N m/s = 1 hp / 745.699872
1 N m/s = 0.00134102208884 hp
1 N m/s = 0.00134102209 hp (approximately)

so where the watt is equal to
1 W = 1 N·m/s
1 W = 0.00134102209 hp

1 kW = 1000 W
1 kW = 1000 x 0.00134102209 hp
1 kW = 1.34102209 hp
