## 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: Therm

The therm (symbol thm) is a non-SI unit of heat energy. It was defined in the United States in 1968 as the energy equivalent of burning 100 cubic feet of natural gas at standard temperature and pressure. In the US gas industry its SI equivalent is defined as exactly 100,000 BTU59°F or 105.4804 megajoules. Public utilities in the U.S. use the therm unit for measuring customer usage of gas and calculating the monthly bills.
