THE ENGLISH SYSTEM
In the English or foot-pound-second (fps) system, the base units are the foot (approximately 30.5 centimeters), the pound (equivalent to about 2.2 kilograms in the gravitational field at the Earth’s surface), the second, the degree Fahrenheit (where water freezes at 32 degrees and boils at 212 degrees at standard sea-level atmospheric pressure), the ampere, the candela, and the mole. The second, the ampere, the candela, and the mole are the same in fps as they are in SI.
