How to Convert Calories to Gigajoules
To convert a measurement in calories to a measurement in gigajoules, multiply the energy by the following conversion ratio: 4.184E-9 gigajoules/calorie.
Since one calorie is equal to 4.184E-9 gigajoules, you can use this simple formula to convert:
gigajoules = calories × 4.184E-9
The energy in gigajoules is equal to the energy in calories multiplied by 4.184E-9.
Calories and gigajoules are both units used to measure energy. Keep reading to learn more about each unit of measure.
What Is a Calorie?
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.

What Is a Gigajoule?
One gigajoule is equal to 1,000,000,000 joules, which is 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 billions, or 109. Gigajoules can be abbreviated as GJ; for example, 1 gigajoule can be written as 1 GJ.
