How to Convert Watt-Hours to Kilowatt-Hours
To convert a measurement in watt-hours to a measurement in kilowatt-hours, divide 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:
kilowatt-hours = watt-hours ÷ 1,000
The energy in kilowatt-hours is equal to the energy in watt-hours divided by 1,000.
Watt-hours and kilowatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
What Is a Watt-Hour?
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.
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.

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.
