How to Convert Kilocalories to Megajoules

To convert a measurement in kilocalories to a measurement in megajoules, multiply the energy by the following conversion ratio: 0.004184 megajoules/kilocalorie.

Since one kilocalorie is equal to 0.004184 megajoules, you can use this simple formula to convert:

megajoules = kilocalories × 0.004184

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

For example, here's how to convert 500 kilocalories to megajoules using the formula above.

megajoules = (500 kcal × 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.

What Is a Kilocalorie?

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.

What Is a Megajoule?

One megajoule is equal to 1,000,000 joules, which is 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 millions, or 106. Megajoules can be abbreviated as MJ; for example, 1 megajoule can be written as 1 MJ.
