Joule [J] to Megawatt-hour [MWh] Converter

Quick Reference

1 Joule (J) = 2.7778e-10 Megawatt-hour (MWh)

1 Megawatt-hour (MWh) = 3600000000 Joule (J)

How to Convert Joule to Megawatt-hour

1 J = 2.7778e-10 MWh
1 MWh = 3600000000 J

To convert Joule to Megawatt-hour, divide the value by 3600000000 (equivalently, multiply by 2.7778e-10). To convert Megawatt-hour back to Joule, multiply by 3600000000.

Example: convert 10 J to MWh:
10 J = 10 x 2.7778e-10 = 2.7778e-9 MWh

Joule

Definition: The joule (symbol: J) is the SI derived unit of energy. It is defined as the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or N⋅m).

History/origin: Named after James Prescott Joule, an English physicist. Joule experimentally determined the mechanical equivalent of heat.

Current use: Used universally in science and engineering to quantify energy, work, and heat. Examples include kinetic energy, potential energy, and heat content of materials.

Megawatt-hour

Definition: A megawatt-hour (symbol MWh) is a unit of energy equal to one megawatt (1,000,000 watts) of power sustained for one hour. It represents a large amount of energy.

History/origin: The megawatt-hour is a derivative of the watt-hour, using the SI prefix 'mega-' to denote a factor of one million. It was developed to represent energy production and consumption on a larger scale.

Current use: Megawatt-hours are used to measure the energy output of large power plants, the energy consumption of large industrial facilities, and the trading of electricity on wholesale markets.
