Megacalorie Conversion Calculator

Enter a value in megacalories below to convert to another unit of energy.

What Is a Megacalorie?

A megacalorie is a unit used to measure energy.

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

How Much 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.

How to Convert Megacalories

To convert megacalories to another unit of energy, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for megacalories in the conversion table below.

Then, multiply the energy measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

megacalories × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
