How to convert Kilojoules to Megajoules
Multiply the kilojoules value by 0.001: 1 kJ = 0.001 MJ. Going the other way, 1 MJ = 1,000 kJ, so divide by 0.001 or use the Megajoules to Kilojoules converter.
About these units
Kilojoules (kJ)
A kilojoule is 1,000 joules. Food energy is labelled in kilojoules in many countries; 1 kJ is about 0.239 kilocalories.
Megajoules (MJ)
A megajoule is one million joules. A kilowatt-hour is 3.6 MJ, and vehicle fuels contain roughly 30 to 45 MJ per liter or kilogram.
