## How to Convert Watt-seconds to Calories

To convert a watt-second measurement to a calorie measurement, multiply the energy by the conversion ratio. One watt-second is equal to 0.239006 calories, so use this simple formula to convert:

The energy in calories is equal to the watt-seconds multiplied by 0.239006.

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

Watt-seconds and calories are both units used to measure energy. Keep reading to learn more about each unit of measure.

## Watt-seconds

The watt-second is a measure of electrical energy equal to one watt of power over a one second period. One watt-second is equal to 1/3,600 of a watt-hour or one joule.

Watt-seconds can be abbreviated as *Ws*, for example 1 watt-second can be written as 1 Ws.

## 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.
