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.

The Hartree energy (symbol Eh) is a physical constant used as atomic unit of energy, named after physicist Douglas Hartree.
