Calories and million BTU 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.

The million BTU is a US customary unit of energy. Million BTU can be abbreviated as MMBTU, for example 1 million BTU can be written as 1 MMBTU.
