How to Convert Calories to Megacalories

To convert a calorie measurement to a megacalorie measurement, multiply the energy by the conversion ratio. One calorie is equal to 1.0E-6 megacalories, so use this simple formula to convert:

megacalories = calories × 1.0E-6

The energy in megacalories is equal to the calories multiplied by 1.0E-6.

For example, here's how to convert 5 calories to megacalories using the formula above.
5 cal = (5 × 1.0E-6) = 5.0E-6 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.
