## How to Convert Megacalories to Kilowatt-hours

To convert a megacalorie measurement to a kilowatt-hour measurement, multiply the energy by the conversion ratio. One megacalorie is equal to 1.162222 kilowatt-hours, so use this simple formula to convert:

The energy in kilowatt-hours is equal to the megacalories multiplied by 1.162222.

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

Megacalories and kilowatt-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.

## Kilowatt-hours

A kilowatt-hour is a measure of electrical energy equal to one kilowatt, or 1,000 watts, of power over a one hour period. Kilowatt-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.

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