## How to Convert Calories to Megacalories

To convert a calorie measurement to a megacalorie measurement, divide the energy by the conversion ratio.

Since one megacalorie is equal to 1,000,000 calories, you can use this simple formula to convert:

megacalories = calories ÷ 1,000,000

The energy in megacalories is equal to the calories divided by 1,000,000.

For example, here's how to convert 500,000 calories to megacalories using the formula above.
500,000 cal = (500,000 ÷ 1,000,000) = 0.5 Mcal

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

## Calories

One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.

When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie."

Calories can be abbreviated as cal; for example, 1 calorie can be written as 1 cal.

## 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.
