## How to Convert Megawatt-Hours to Megacalories

To convert a measurement in megawatt-hours to a measurement in megacalories, multiply the energy by the following conversion ratio: 860.42065 megacalories/megawatt-hour.

Since one megawatt-hour is equal to 860.42065 megacalories, you can use this simple formula to convert:

megacalories = megawatt-hours × 860.42065

The energy in megacalories is equal to the energy in megawatt-hours multiplied by 860.42065.

For example, here's how to convert 5 megawatt-hours to megacalories using the formula above.
megacalories = (5 MWh × 860.42065) = 4,302.10325 Mcal

### How Many Megacalories Are in a Megawatt-Hour?

There are 860.42065 megacalories in a megawatt-hour, which is why we use this value in the formula above.

1 MWh = 860.42065 Mcal

## 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 Megacalorie?

One megacalorie is equal to 1,000,000 calories, which is 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.
