How to convert Megajoules to Calories
Multiply the megajoules value by 239,006: 1 MJ = 239,006 cal. Going the other way, 1 cal = 4.184e-6 MJ, so divide by 239,006 or use the Calories to Megajoules converter.
About these units
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.
Calories (cal)
The calorie used here is the thermochemical calorie, exactly 4.184 joules, roughly the energy needed to warm one gram of water by one degree Celsius. Food calories are actually kilocalories.
