Convert calorie (th) to gigajoule
Please provide values below to convert calorie (th) [cal (th)] to gigajoule [GJ], or Convert gigajoule to calorie (th).
1 cal (th) = 4.184e-09 GJ. To convert calorie (th) to gigajoule, multiply the value by 4.184e-09; to go the other way, divide by it (1 GJ = 239005736.138 cal (th)). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 cal (th) = 4.184e-09 GJ
- 1 GJ = 239005736.138 cal (th)
- 10 cal (th) = 4.184e-08 GJ
- 100 cal (th) = 4.184e-07 GJ
How to Convert Calorie (Th) to Gigajoule
1 cal (th) = 4.184e-09 GJ
Example: convert 15 cal (th) to GJ:
15 cal (th) = 15 × 4.184e-09 GJ = 6.276e-08 GJ

Calorie (Th)
The calorie (th) is a unit of energy used to quantify the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie (th) was historically used in the context of thermochemistry and nutrition, originating from the calorie concept in the 19th century. It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.
Current Use
Today, the calorie (th) is primarily used in nutrition labeling and food energy measurements, especially in regions where the thermochemical calorie is still recognized, although the joule is the SI standard.
Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
