## How to Convert Watt-Hours to Megacalories

To convert a measurement in watt-hours to a measurement in megacalories, multiply the energy by the following conversion ratio: 0.00086 megacalories/watt-hour.

Since one watt-hour is equal to 0.00086 megacalories, you can use this simple formula to convert:

The energy in megacalories is equal to the energy in watt-hours multiplied by 0.00086.

**For example,**here's how to convert 5,000 watt-hours to megacalories using the formula above.

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

## 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]}

## 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.
