Formula
1 W = 0.001 kW
Power measures how quickly energy is used or produced. Watts, kilowatts, horsepower, and BTU per hour are common in motors, appliances, vehicles, pumps, HVAC equipment, and generators.
A converted power value is useful for comparing labels, but equipment selection also depends on duty cycle, efficiency, load, and operating conditions.
Power measures the rate of energy use or output. The converter changes the unit used for that rate, such as horsepower to kilowatts, while keeping the represented rate equivalent.
