Full bio

A kilowatt-hour is a unit used to measure energy.

Kilowatt-hours are usually abbreviated as kWh, although the formally adopted expression is kW·h. The abbreviation kW h is also sometimes used. For example, 1 kilowatt-hour can be written as 1 kWh, 1 kW·h, or 1 kW h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.[1]

How Much Is a Kilowatt-Hour?

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.

How to Convert Kilowatt-Hours

To convert kilowatt-hours to another unit of energy, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[2]

You can find the conversion factors for kilowatt-hours in the conversion table below.

Then, multiply the energy measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

kilowatt-hours × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
