A quad is a unit of energy equal to 10^15 (a short-scale quadrillion) BTU, or 1.055 x 10^18 joules (1.055 exajoules or EJ) in SI units. The unit is used by the U.S. Department of Energy in discussing world and national energy budgets. The global primary energy production in 2004 was 446 quad, equivalent to 471 EJ.

Symbol/abbreviation: quad
Unit of: ENERGY
ENERGY's base unit: joules (Non-SI/Derived Unit)
In relation to the base unit (joules), 1 Quads = 1.05505585262E+18 joules.
