Meaning and Definition
A unit of energy, precisely the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius at standard atmospheric pressure.
Also known as a gram calorie, it is a precise scientific measurement of energy, distinct from the large Calorie (kilocalorie) used in food. It is a foundational unit in physics, chemistry, and biology for quantifying thermal energy transfer.

Common Mistakes When Using “small calorie”
- Using 'calorie' alone to mean 'small calorie' in a nutritional context (where it always means kilocalorie).

- Confusing it with the joule (1 small calorie ≈ 4.184 joules).
FAQ
Frequently Asked Questions
In common usage, 'calorie' (often written with a capital C) means kilocalorie, used for food energy. 'Small calorie' (or gram calorie) is the scientific unit, 1/1000th of a food Calorie.
Yes, but often alongside or in definition of the joule, the SI unit of energy. It remains a useful unit in specific fields like chemistry and physics.
Because its definition is based on heating one gram of water.
No. For clarity and precision, you must use 'small calorie' or 'gram calorie' if that is the unit you mean, as 'calorie' alone is ambiguous.
A unit of energy, precisely the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius at standard atmospheric pressure.
