Power

kW to W conversion

Convert kilowatt (kW) to watt (W). Power is energy per unit time — the rating of pumps, compressors, motors, and heat duties.

1 kW = 1000 W

Formula

To convert kilowatt to watt, multiply the kW value by 1000. To go the other way, divide by 1000 (or multiply by 0.001).

Used in practice

Rotating-equipment duties are quoted in kW or hp; heat duties in kW, MW, or BTU/hr.

Electrical input, shaft power, and hydraulic power differ by the efficiencies between them — label which one a number refers to.

Worked example. A power of 100 kW is 100000 W.
