How to Convert Megacalories to Megawatt-hours

To convert a megacalorie measurement to a megawatt-hour measurement, multiply the energy by the conversion ratio. One megacalorie is equal to 0.001162 megawatt-hours, so use this simple formula to convert:

megawatt-hours = megacalories × 0.001162

The energy in megawatt-hours is equal to the megacalories multiplied by 0.001162.

For example, here's how to convert 500 megacalories to megawatt-hours using the formula above.
500 Mcal = (500 × 0.001162) = 0.581111 MWh

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


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.


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]
