# Megacalories to Watt-hours Conversion

Enter the energy in megacalories below to get the value converted to watt-hours.

Results in Watt-hours: 1 Mcal = 1,162.222222 Wh

## How to Convert Megacalories to Watt-hours

To convert a megacalorie measurement to a watt-hour measurement, multiply the energy by the conversion ratio.

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 megacalories multiplied by 1,162.222222.

For example, here's how to convert 5 megacalories to watt-hours using the formula above.
5 Mcal = (5 × 1,162.222222) = 5,811.111111 Wh

## 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.
