How to Convert Million BTU to Calories

To convert a million BTU measurement to a calorie measurement, multiply the energy by the conversion ratio. One million BTU is equal to 252,164,400.7218 calories, so use this simple formula to convert:

calories = million BTU × 252,164,400.7218

The energy in calories is equal to the million BTU multiplied by 252,164,400.7218.

For example, here's how to convert 5 million BTU to calories using the formula above.
5 MMBTU = (5 × 252,164,400.7218) = 1,260,822,003.609 cal

Million BTU and calories are both units used to measure energy. Keep reading to learn more about each unit of measure.

Million BTU

One million BTU is a measure of heat energy equal to 1,000,000 BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit.

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.

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.
