Foot-pounds (ft⋅lb)
Definition
A foot-pound (ft⋅lb) is an imperial unit of energy equal to the work done when a force of one pound-force moves an object one foot. It equals approximately 1.35582 joules.
History
The foot-pound has been used in English-speaking countries since the early days of mechanical engineering. It was the standard unit for torque and mechanical work before the joule gained prominence.
Current use
Foot-pounds are widely used in the US for measuring torque in automotive and mechanical applications, firearm muzzle energy, and mechanical work in engineering specifications.
Watt-hours (Wh)
Definition
A watt-hour (Wh) is a unit of energy equal to the work done by one watt of power sustained for one hour. It equals 3,600 joules.
History
The watt-hour emerged with the development of electrical power systems in the late 19th century. It provided a practical way to measure and bill for electrical energy consumption.
Current use
Watt-hours are used for small battery capacities (e.g., phone batteries, portable electronics) and as a base unit for kilowatt-hours used in household electricity metering.
