How to Convert Power Units
To perform a conversion, look up the target unit's conversion factor relative to the base unit (watt). Below are the exact mathematical formulas for the most common power unit pairs:
Kilowatt to Horsepower (HP)
hp = kW × 1.341022089 Horsepower (HP) to Kilowatt
kW = hp × 0.745699872 Watt to Kilowatt
kW = W × 0.001 Watt to Kilowatt
kW = W × 0.001 Power Unit Conversion Charts
