How to Convert Calories to Megawatt-hours

To convert a calorie measurement to a megawatt-hour measurement, multiply the energy by the conversion ratio. One calorie is equal to 1.1622E-9 megawatt-hours, so use this simple formula to convert:

megawatt-hours = calories × 1.1622E-9

The energy in megawatt-hours is equal to the calories multiplied by 1.1622E-9.

For example, here's how to convert 5 calories to megawatt-hours using the formula above.
5 cal = (5 × 1.1622E-9) = 5.8111E-9 MWh

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


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.


A megawatt-hour is a measure of electrical energy equal to one megawatt, or 1,000,000 watts, of power over a one hour period. Megawatt-hours are a measure of electrical work performed over a period of time, and are often used as a way of measuring energy usage by electric companies.

Megawatt-hours can be abbreviated as MWh, for example 1 megawatt-hour can be written as 1 MWh.
