## How to Convert Calories to Watt-hours

To convert a calorie measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One calorie is equal to 0.001162 watt-hours, so use this simple formula to convert:

The energy in watt-hours is equal to the calories multiplied by 0.001162.

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

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

## Calories

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.

## Watt-hours

The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.

Watt-hours can be abbreviated as *Wh*, for example 1 watt-hour can be written as 1 Wh.
