## How to Convert Kilocalories to Gigajoules

To convert a kilocalorie measurement to a gigajoule measurement, multiply the energy by the conversion ratio. One kilocalorie is equal to 4.184E-6 gigajoules, so use this simple formula to convert:

The energy in gigajoules is equal to the kilocalories multiplied by 4.184E-6.

**For example,**here's how to convert 500,000 kilocalories to gigajoules using the formula above.

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

## 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.

## Gigajoules

One gigajoule is equal to 1,000,000,000 joules, which are the energy equal to the force on an object of one newton at a distance of one meter.

The gigajoule is a multiple of the joule, which is the SI derived unit for energy. In the metric system, "giga" is the prefix for 10^{9}. Gigajoules can be abbreviated as *GJ*; for example, 1 gigajoule can be written as 1 GJ.
