How to Convert Megacalories to Gigajoules

To convert a megacalorie measurement to a gigajoule measurement, multiply the energy by the conversion ratio.

Since one megacalorie is equal to 0.004184 gigajoules, you can use this simple formula to convert:

gigajoules = megacalories × 0.004184

The energy in gigajoules is equal to the megacalories multiplied by 0.004184.

For example, here's how to convert 500 megacalories to gigajoules using the formula above.
500 Mcal = (500 × 0.004184) = 2.092 GJ

Megacalories and gigajoules 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.

Gigajoules

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

The gigajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "giga" is the prefix for 109. Gigajoules can be abbreviated as GJ; for example, 1 gigajoule can be written as 1 GJ.
