## How to Convert Joules to Kilocalories

To convert a joule measurement to a kilocalorie measurement, multiply the energy by the conversion ratio. One joule is equal to 0.000239 kilocalories, so use this simple formula to convert:

The energy in kilocalories is equal to the joules multiplied by 0.000239.

**For example,**here's how to convert 5 joules to kilocalories using the formula above.

Joules and kilocalories are both units used to measure energy. Keep reading to learn more about each unit of measure.

## Joules

The joule is the energy equal to the force on an object of one newton at a distance of one meter. One joule is equal to the heat energy dissipated by the current of one ampere through one ohm of resistance for one second.

One joule is also equal to the energy needed to move an electric charge of one coulomb through a potential difference of one volt. In addition, one joule is also equal to the one watt-second.

The joule is the SI derived unit for energy in the metric system. Joules can be abbreviated as *J*, for example 1 joule can be written as 1 J.

## Kilocalories

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.
