How to Convert Megacalories to Megajoules

To convert a megacalorie measurement to a megajoule measurement, multiply the energy by the conversion ratio. One megacalorie is equal to 4.184 megajoules, so use this simple formula to convert:

megajoules = megacalories × 4.184

The energy in megajoules is equal to the megacalories multiplied by 4.184.

For example, here's how to convert 5 megacalories to megajoules using the formula above.
5 Mcal = (5 × 4.184) = 20.92 MJ

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

Megacalories

One megacalorie is equal to 1,000,000 calories, which are 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.

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 109. Megajoules can be abbreviated as MJ, for example 1 megajoule can be written as 1 MJ.
