How to Convert Kilocalories to Megajoules

To convert a kilocalorie measurement to a megajoule measurement, multiply the energy by the conversion ratio. One kilocalorie is equal to 0.004184 megajoules, so use this simple formula to convert:

megajoules = kilocalories × 0.004184

The energy in megajoules is equal to the kilocalories multiplied by 0.004184.

For example, here's how to convert 500 kilocalories to megajoules using the formula above.
500 kcal = (500 × 0.004184) = 2.092 MJ

Kilocalories and megajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.

Kilocalories

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal, for example 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.

Megajoules

One megajoule is equal to 1,000,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.

The megajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "mega" is the prefix for 106. Megajoules can be abbreviated as MJ, for example 1 megajoule can be written as 1 MJ.
