A lower-case calorie, or small calorie, is the amount of energy required to heat one gram of water by one degree Celsius. This can vary depending on the temperature of water, but the ISO defines a calorie as 4.184 joules.

This unit should not be confused with an upper-case Calorie, or kilocalorie, which is commonly used in food labeling.

Joules

A joule is the standard unit of energy.

On the surface of the Earth, it takes about 9.8 joules to lift a 1 kilogram object by 1 meter.
