Power Converter
Convert power units through watts. The horsepower option uses mechanical horsepower, which must not be mixed with metric horsepower without adjustment.
Worked example
1,000 W = 1 kW = 1.34102209 mechanical hp.
Important interpretation
Power is a rate of energy transfer. Do not compare a kW value directly with a kWh value without including time.
