Quad Definition and Usage

One therm is a measure of heat energy equal to one quadrillion (1,000,000,000,000,000) BTU, which are equal to the amount of heat energy required to increase the temperature of one pound of water one degree Fahrenheit. Quads are usually used when talking about energy resources and consumption on a national or international scale.

The quad is a US customary unit of energy.
