## How to Convert Megacalories to Watt-hours

To convert a megacalorie measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One megacalorie is equal to 1,162.222222 watt-hours, so use this simple formula to convert:

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

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

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

## 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.

## 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]}
