How to Convert Kilocalories to Megawatt-Hours

To convert a measurement in kilocalories to a measurement in megawatt-hours, multiply the energy by the following conversion ratio: 1.1622E-6 megawatt-hours/kilocalorie.

Since one kilocalorie is equal to 1.1622E-6 megawatt-hours, you can use this simple formula to convert:

megawatt-hours = kilocalories × 1.1622E-6

The energy in megawatt-hours is equal to the energy in kilocalories multiplied by 1.1622E-6.

For example, here's how to convert 500,000 kilocalories to megawatt-hours using the formula above.
megawatt-hours = (500,000 kcal × 1.1622E-6) = 0.581111 MWh

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

What Is a Kilocalorie?

One kilocalorie, is equal to the heat needed to raise the temperature of one kilogram of water from 14.5 to 15.5 degrees Celsius.

Kilocalories can be abbreviated as kcal; for example, 1 kilocalorie can be written as 1 kcal.

When being used to measure nutrition or metabolic processes, the large calorie is used, which is equal to one kilocalorie.

What Is a Megawatt-Hour?

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

Megawatt-hours are usually abbreviated as MWh, although the formally adopted expression is MW·h. The abbreviation MW h is also sometimes used. For example, 1 megawatt-hour can be written as 1 MWh, 1 MW·h, or 1 MW 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]
