Watts to kilowatts
Multiply watts by 0.001 to get kilowatts.
5,000 W = 5 kW
How to convert watts to kilowatts
The kilowatt is one thousand watts — the metric unit for engine and appliance power. The watt is the SI unit of power, one joule per second.
Worked example — 5,000 W: 5,000 × 0.001 = 5 kW.

About watts and kilowatts
Watt (W)
1 W = 0.001 kWDefinition. The SI unit of power, one joule per second
History and origin
The watt is the SI unit of power, one joule per second, named after James Watt for his work on the steam engine. It measures the rate at which energy is used or produced.
Current use
Watts rate light bulbs, appliances and solar panels the world over.
Source: NIST SP 811, App. B (power). Mechanical hp = 550 ft·lbf/s ≈ 745.70 W; metric hp (PS) = 75 kgf·m/s = 735.49875 W
Kilowatt (kW)
1 kW = 1,000 WDefinition. One thousand watts — the metric unit for engine and appliance power
History and origin
The kilowatt is one thousand watts, a metric multiple of the SI power unit. It gives practical numbers for engines and appliances.
Current use
Kilowatts rate car engines outside the United States, large appliances and electric-vehicle charging.
Source: NIST SP 811, App. B (power). Mechanical hp = 550 ft·lbf/s ≈ 745.70 W; metric hp (PS) = 75 kgf·m/s = 735.49875 W
Where people use this
Watts: light bulbs, appliances, solar panels. Kilowatts: car engines outside the US, appliances, EV charging. 1000 W is exactly 1 kW.
