Watt [W] to Kilowatt [kW] Converter
Quick Reference
1 Watt (W) = 0.001 Kilowatt (kW)
1 Kilowatt (kW) = 1000 Watt (W)
How to Convert Watt to Kilowatt
1 W = 0.001 kW
1 kW = 1000 W
To convert Watt to Kilowatt, divide the value by 1000 (equivalently, multiply by 0.001). To convert Kilowatt back to Watt, multiply by 1000.
Example: convert 10 W to kW:
10 W = 10 x 0.001 = 0.01 kW
Watt
Definition: The watt (W) is the derived unit of power in the International System of Units (SI). It is defined as one joule per second and represents the rate at which energy is transferred or converted.
History/origin: The watt is named in honor of Scottish inventor James Watt, who significantly improved the steam engine. The unit was adopted by the Second Congress of the British Association for the Advancement of Science in 1882.
Current use: Watts are used universally to measure power consumption and generation in electrical and mechanical systems. It is a fundamental unit for specifying the power rating of appliances, light bulbs, and engines.
Kilowatt
Definition: A kilowatt (kW) is a unit of power equal to one thousand (10³) watts. It is a multiple of the base unit, the watt, in the International System of Units (SI).
History/origin: The watt is named in honor of Scottish inventor James Watt. The kilowatt, as a decimal multiple of the watt, was derived as a larger unit for measuring significant amounts of power.
Current use: Kilowatts are used to measure the power consumption of appliances, electric motors, and industrial equipment. It is also used to measure the power output of generators and engines.
