## ››Definition: Calorie

A calorie refers to a non-SI unit of energy. There are two common but different meanings: one is used in food and nutrition, the other was formerly widely used in chemistry, and a food calorie represents 1000 chemistry calories. The food calorie is sometimes capitalized as Calorie to distinguish it from the chemistry calorie; however, this capitalization is rarely observed in practice.

## ››Definition: Zeptojoule

The SI prefix "zepto" represents a factor of 10-21, or in exponential notation, 1E-21.

So 1 zeptojoule = 10-21 joules.

The definition of a joule is as follows:

The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).
