To convert a measurement in megacalories to a measurement in kilojoules, multiply the energy by the following conversion ratio: 4,184 kilojoules/megacalorie.

Since one megacalorie is equal to 4,184 kilojoules, you can use this simple formula to convert:

kilojoules = megacalories × 4,184

The energy in kilojoules is equal to the energy in megacalories multiplied by 4,184.

For example, here's how to convert 5 megacalories to kilojoules using the formula above.
kilojoules = (5 Mcal × 4,184) = 20,920 kJ

How Many Kilojoules Are in a Megacalorie?

There are 4,184 kilojoules in a megacalorie, which is why we use this value in the formula above.

1 Mcal = 4,184 kJ

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

What is a Megacalorie?

One megacalorie is equal to 1,000,000 calories, which is the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius. One megacalorie is equal to 4.184 megajoules.

Megacalories can be abbreviated as Mcal; for example, 1 megacalorie can be written as 1 Mcal.

What is a Kilojoule?

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

The kilojoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "kilo" is the prefix for thousands, or 103. Kilojoules can be abbreviated as kJ; for example, 1 kilojoule can be written as 1 kJ.
