## How to Convert Joules to Megacalories

To convert a measurement in joules to a measurement in megacalories, divide the energy by the following conversion ratio: 4,184,000 joules/megacalorie.

Since one megacalorie is equal to 4,184,000 joules, you can use this simple formula to convert:

megacalories = joules ÷ 4,184,000

The energy in megacalories is equal to the energy in joules divided by 4,184,000.

**For example,**here's how to convert 5,000,000 joules to megacalories using the formula above.

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

## What Is a Joule?

The joule is the energy equal to the force on an object of one newton at a distance of one meter.^{[1]} One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*; for example, 1 joule can be written as 1 J.

## 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.
