What is kilowatt (kW)?

Kilowatt (symbol: kW) is a unit of electric power.


Kilowatt definition

One kilowatt (kW) is equal to 1000 watts (W):

1kW = 1000W

One kilowatt is defined as energy consumption of 1000 joules for 1 second:

1kW = 1000J / 1s

One kilowatt is equal to 1000000 milliwatts:

1kW = 1000000mW


Kilowatt examples

Example #1

What is the power consumption in kW when energy of 30000 joules was released during 10 seconds?


P(kW) = 30000J / 10s / 1000 = 3kW


Example #2

What is the power consumption when consuming 6kWh for 3 hours?


P(kW) = 6kWh / 3h = 2kW
