Kilojoule [kJ] to Megawatt-hour [MWh] Converter

Quick Reference

1 Kilojoule (kJ) = 2.7778e-7 Megawatt-hour (MWh)

1 Megawatt-hour (MWh) = 3600000 Kilojoule (kJ)

How to Convert Kilojoule to Megawatt-hour

1 kJ = 2.7778e-7 MWh
1 MWh = 3600000 kJ

To convert Kilojoule to Megawatt-hour, divide the value by 3600000 (equivalently, multiply by 2.7778e-7). To convert Megawatt-hour back to Kilojoule, multiply by 3600000.

Example: convert 10 kJ to MWh:
10 kJ = 10 x 2.7778e-7 = 2.7778e-6 MWh

↔ Convert Megawatt-hour to Kilojoule

Kilojoule

Definition: A kilojoule (symbol: kJ) is equal to 1000 joules. It's a unit of energy.

History/origin: Based on the joule, using the SI prefix 'kilo-' to denote a factor of one thousand.

Current use: Commonly used to express the energy content of food, fuels, and other substances when the joule would be impractically small. Also used in thermodynamics and other areas of physics and engineering.

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.
