How to Convert Kilojoules to Megawatt-hours
The kilojoule and megawatt-hour are both units of energy. 1 megawatt-hour equals 3600000 kilojoules. This means to convert kilojoules to megawatt-hours, you divide by 3600000.
Formula
Step-by-Step Example
Convert 5 kJ to megawatt-hours:
We need to convert kilojoules to megawatt-hours
Since 1 MWh = 3600000 kJ, divide by 3600000
5 ÷ 3600000 = 1.3888888889e-6
5 kJ = 1.3888888889e-6 MWh

About These Units
Kilojoule (kJ)
A kilojoule (kJ) equals 1,000 joules or approximately 239 calories. Kilojoules measure food energy on nutrition labels in Australia, Europe, and many countries. An average adult needs 8,400-10,000 kJ daily. One kJ equals approximately 0.239 kcal.
Megawatt-hour (MWh)
A megawatt-hour (MWh) equals 1,000 kilowatt-hours or 3.6 gigajoules. MWh measures power plant output, large industrial energy use, and utility-scale batteries. An average US home uses about 10.5 MWh annually. Wind turbines produce 2-4 MWh per hour.
