How to Convert kWh to MJ

The Megajoule (MJ)

The megajoule (MJ) is a unit of energy, is equal to one million (106) joules which are both SI measurements. It refers to the energy expended; or the work done to exert force. The megajoule as a unit of measurement is named after the English physicist James Prescott Joule. The relationship between one joule and the watt can be summarised as the work required to produce one watt of power per second. The calculation of Watts/hour for an appliance will give you an idea of how much energy is consumed per day. The kWh is equivalent to 1000 watt hours.

The Kilowatt Hour (kWh)

The kWh or kilowatt hour is similarly a unit of unit of energy. The kWh is equal to 1000 watt hours or 3.6 megajoules. The kWh is a standard billing unit for utility companies as electricity consumption is expressed in kWh. With an increasing emphasis on energy efficiency energy smart meters or specifically kWh meters can be purchased to give accurate electricity comsumption readings. At it's basic the energy flow is monitored through the use of a Kwh or smart meter. With the current increase in energy prices the monitoring of energy useage is significant. Real time data and historical data are displayed. A cost indicator is also a feature.

Conversion Calculator

There are easy to use conversion calculators online which can convert Kwh data to megajoules accurately. 1kWh is equivalent to 3.6MJ at a conversion rate of 1mj = 0.2777777777778 Kwh. has an energy conversion calculator which can be used on the website.
