How to Convert Watt-hours to Kilowatt-hours

conversion scale showing watt-hours and equivalent kilowatt-hours energy values

To convert a watt-hour measurement to a kilowatt-hour measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 0.001 kilowatt-hours, so use this simple formula to convert:

kilowatt-hours = watt-hours × 0.001

The energy in kilowatt-hours is equal to the watt-hours multiplied by 0.001.

For example, here's how to convert 5 watt-hours to kilowatt-hours using the formula above.

5 Wh = (5 × 0.001) = 0.005 kWh

Watt-hours and kilowatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.

Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as Wh, for example 1 watt-hour can be written as 1 Wh.

A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Kilowatt-hours can be abbreviated as kWh, for example 1 kilowatt-hour can be written as 1 kWh.
