## How to Convert Watt-hours to Megacalories

To convert a watt-hour measurement to a megacalorie measurement, multiply the energy by the conversion ratio. One watt-hour is equal to 0.00086 megacalories, so use this simple formula to convert:

The energy in megacalories is equal to the 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.

## Watt-hours

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]}

## Megacalories

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.
