ConverterWatts to Kilowatts Converter
Rescale a power value from watts to kilowatts without adding voltage, phase, power factor, or efficiency assumptions. This is an exact SI-prefix conversion.
Divide watts by 1000. Signed values are accepted as mathematical power values. Results display up to six decimal places.
The SI Prefix Does The Work
kW = W / 1000. For example, 2500 W is 2.5 kW and 1 W is 0.001 kW. The calculation changes the scale, not the physical quantity.
Power Is Not Energy
Kilowatts describe power. Kilowatt-hours describe energy accumulated over time. Converting W to kW does not calculate consumption, cost, or runtime.
Frequently Asked Questions
One kilowatt is exactly 1000 watts, so divide watts by 1000 to obtain kilowatts.
No. kW is power, while kWh is energy over time. This page does not use a duration.
