Convert calorie (th) to microjoule
Please provide values below to convert calorie (th) [cal (th)] to microjoule [µJ], or Convert microjoule to calorie (th).
1 cal (th) = 4184000 µJ. To convert calorie (th) to microjoule, multiply the value by 4184000; to go the other way, divide by it (1 µJ = 2.39005736138e-07 cal (th)). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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 It has largely been replaced by the joule in scientific contexts but remains in common use in some regions and fields.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.
Microjoule
A microjoule (µJ) is a unit of energy equal to one millionth of a joule, used to measure small amounts of energy.
History/Origin
The microjoule was introduced as part of the metric system to facilitate the measurement of very small energy quantities, especially in scientific and engineering contexts, with the adoption of the International System of Units (SI).
Current Use
Microjoules are commonly used in fields such as electronics, physics, and biology to quantify small energy transfers, signals, or reactions, often in research and technical applications.
