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

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

joules = megacalories × 4,184,000

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

For example, here's how to convert 5 megacalories to joules using the formula above.
5 Mcal = (5 × 4,184,000) = 20,920,000 J

How Many Joules Are in a Megacalorie?

There are 4,184,000 joules in a megacalorie, which is why we use this value in the formula above.

1 Mcal = 4,184,000 J

Megacalories and joules 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 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.
