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.

Thermies (FR)

Definition

A thermie is a French unit of heat energy equal to 1,000 kilocalories, or approximately 4,184,000 joules. It was historically used in French engineering and heating systems.

History

The thermie was used in France and other French-speaking countries throughout the 20th century for industrial heating and energy calculations, before the widespread adoption of joules and kilowatt-hours.

Current use

The thermie is now largely obsolete but may still appear in older French engineering documentation, historical heating system specifications, and some regulatory texts.
