## How to Convert Calories to Kilowatt-Hours

To convert a measurement in calories to a measurement in kilowatt-hours, multiply the energy by the following conversion ratio: 1.1622E-6 kilowatt-hours/calorie.

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

kilowatt-hours = calories × 1.1622E-6

The energy in kilowatt-hours is equal to the energy in calories multiplied by 1.1622E-6.

**For example,**here's how to convert 500,000 calories to kilowatt-hours using the formula above.

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

## What Is a Calorie?

One calorie is equal to the heat needed to raise the temperature of one gram of water from 14.5 to 15.5 degrees Celsius.

When measuring the energy content in foods, the large calorie, or kilocalorie is used, but it's often still just called a "calorie." When both the calorie and large calorie are used in the same context it is common to refer to the calorie as a "small calorie."

Calories can be abbreviated as *cal*; for example, 1 calorie can be written as 1 cal.

## What Is a Kilowatt-Hour?

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]}
