How to Convert Gigajoules to Kilocalories

To convert a gigajoule measurement to a kilocalorie measurement, multiply the energy by the conversion ratio. One gigajoule is equal to 239,005.736138 kilocalories, so use this simple formula to convert:

kilocalories = gigajoules × 239,005.736138

The energy in kilocalories is equal to the gigajoules multiplied by 239,005.736138.

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

5 GJ = (5 × 239,005.736138) = 1,195,028.680688 kcal

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

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 10⁶. Gigajoules can be abbreviated as GJ, for example 1 gigajoule can be written as 1 GJ.

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.
