## How to Convert Joules to Kilowatt-Hours

To convert a measurement in joules to a measurement in kilowatt-hours, divide the energy by the following conversion ratio: 3,600,000 joules/kilowatt-hour.

Since one kilowatt-hour is equal to 3,600,000 joules, you can use this simple formula to convert:

kilowatt-hours = joules ÷ 3,600,000

The energy in kilowatt-hours is equal to the energy in joules divided by 3,600,000.

**For example,**here's how to convert 5,000,000 joules to kilowatt-hours using the formula above.

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

## What Is a Joule?

The joule is the energy equal to the force on an object of one newton at a distance of one meter.^{[1]} One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*; for example, 1 joule can be written as 1 J.

## 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]}
