How to Convert Joules to Kilowatt-hours
To convert a joule measurement to a kilowatt-hour measurement, divide the energy by the conversion ratio. One kilowatt-hour is equal to 3,600,000 joules, so use this simple formula to convert:
The energy in kilowatt-hours is equal to the joules divided by 3,600,000.
Joules and kilowatt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one 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.
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.
