How to Convert Megawatt-Hours to Calories

To convert a measurement in megawatt-hours to a measurement in calories, multiply the energy by the following conversion ratio: 860,420,650.0956 calories/megawatt-hour.

Since one megawatt-hour is equal to 860,420,650.0956 calories, you can use this simple formula to convert:

calories = megawatt-hours × 860,420,650.0956

The energy in calories is equal to the energy in megawatt-hours multiplied by 860,420,650.0956.

For example, here's how to convert 5 megawatt-hours to calories using the formula above.
calories = (5 MWh × 860,420,650.0956) = 4,302,103,250.478 cal

What Is a Megawatt-Hour?

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 are usually abbreviated as MWh, although the formally adopted expression is MW·h. The abbreviation MW h is also sometimes used. For example, 1 megawatt-hour can be written as 1 MWh, 1 MW·h, or 1 MW h.

In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.[1]

What Is a Calorie?

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.
