How to Convert Kilowatt-Hours to Watt-Hours

To convert a measurement in kilowatt-hours to a measurement in watt-hours, multiply the energy by the following conversion ratio: 1,000 watt-hours/kilowatt-hour.

Since one kilowatt-hour is equal to 1,000 watt-hours, you can use this simple formula to convert:

watt-hours = kilowatt-hours × 1,000

The energy in watt-hours is equal to the energy in kilowatt-hours multiplied by 1,000.

For example, here's how to convert 5 kilowatt-hours to watt-hours using the formula above.
watt-hours = (5 kWh × 1,000) = 5,000 Wh

What 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.

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]

What Is a Watt-Hour?

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

Watt-hours are usually abbreviated as Wh, although the formally adopted expression is W·h. The abbreviation W h is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.
