## How to Convert Megacalories to Watt-Hours

To convert a measurement in megacalories to a measurement in watt-hours, multiply the energy by the following conversion ratio: 1,162.222222 watt-hours/megacalorie.

Since one megacalorie is equal to 1,162.222222 watt-hours, you can use this simple formula to convert:

watt-hours = megacalories × 1,162.222222

The energy in watt-hours is equal to the energy in megacalories multiplied by 1,162.222222.

**For example,**here's how to convert 5 megacalories to watt-hours using the formula above.

### How Many Watt-Hours Are in a Megacalorie?

There are **1,162.222222** watt-hours in a megacalorie, which is why we use this value in the formula above.

1 Mcal = 1,162.222222 Wh

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

## 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.

## What Is a Watt-Hour?

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours are usually abbreviated as *Wh*, although the formally adopted expression is *W·h*. The abbreviation *W h* is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W 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]}
