Convert kilowatt-hour to megajoule
Please provide values below to convert kilowatt-hour [kW*h] to megajoule [MJ], or Convert megajoule to kilowatt-hour.
1 kW*h = 3.6 MJ. To convert kilowatt-hour to megajoule, multiply the value by 3.6; to go the other way, divide by it (1 MJ = 0.277777777778 kW*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW*h = 3.6 MJ
- 1 MJ = 0.277777777778 kW*h
- 10 kW*h = 36 MJ
- 100 kW*h = 360 MJ
How to Convert Kilowatt-Hour to Megajoule
1 kW*h = 3.6 MJ
Example: convert 15 kW*h to MJ:
15 kW*h = 15 × 3.6 MJ = 54 MJ

Kilowatt-Hour
A kilowatt-hour (kW·h) is a unit of energy equal to the energy transferred or used when a power of one kilowatt is sustained for one hour.
History/Origin
The kilowatt-hour originated in the late 19th century with the development of electrical power systems, becoming a standard unit for measuring electrical energy consumption and billing.
Current Use
It is widely used today in electricity billing, energy consumption monitoring, and in various engineering and scientific applications to quantify electrical energy usage.
Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
