This power unit converter is an essential calculation tool designed for engineers mechanics physicists and students. It allows you to swiftly and accurately translate energy transfer rates across multiple measurement standards including watts kilowatts megawatts and mechanical horsepower.
Power Unit Conversion Formula
Power measures the rate at which work is done or energy is transferred. In the International System of Units the base unit for power is the watt. All other power measurements can be converted by multiplying or dividing by their specific structural ratio to the base watt.
1 Kilowatt (kW) = 1000 Watts (W)
1 Mechanical Horsepower (hp) = 745.699872 Watts (W)
To convert from a larger unit to a smaller unit you multiply the value. To convert from a smaller unit to a larger unit you divide.
Kilowatt to Horsepower Formula
A very common calculation in the automotive and electrical engineering sectors is translating kilowatts into mechanical horsepower. Because one horsepower equals roughly 745.7 watts and a kilowatt is exactly 1000 watts the conversion factor is approximately 1.341.
Horsepower = Kilowatts x 1.34102
Example: An electric motor rated at 50 kilowatts produces mechanical power. You multiply 50 by 1.34102 which gives you an output of approximately 67.05 horsepower.
