Convert calorie (th) to joule
Please provide values below to convert calorie (th) [cal (th)] to joule [J], or Convert joule to calorie (th).
1 cal (th) = 4.184 J. To convert calorie (th) to joule, multiply the value by 4.184; to go the other way, divide by it (1 J = 0.239005736138 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) = 4.184 J
- 1 J = 0.239005736138 cal (th)
- 10 cal (th) = 41.84 J
- 100 cal (th) = 418.4 J
How to Convert Calorie (Th) to Joule
1 cal (th) = 4.184 J
Example: convert 15 cal (th) to J:
15 cal (th) = 15 × 4.184 J = 62.76 J

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 It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.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.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
