Foot-Pound
A foot-pound is a unit of energy or work equal to the work done when a force of one pound-force is exerted over a distance of one foot.
History/Origin
The foot-pound has been used primarily in the United States and the United Kingdom as a customary unit of energy, originating from imperial and US customary measurement systems, before the widespread adoption of the SI system.
Current Use
Today, the foot-pound is still used in certain fields such as engineering, automotive, and aerospace industries in the US for expressing torque and energy, although the SI unit joule is more common internationally.
Horsepower Hour
A horsepower hour (hp*h) is a unit of energy representing the amount of energy equivalent to one horsepower of power sustained over one hour of time.
History/Origin
The horsepower hour originated from the traditional unit of horsepower used to quantify engine power, combined with the hour to measure energy consumption or production over time. It has been used primarily in engineering and energy industries to express energy usage or capacity.
Current Use
Today, the horsepower hour is rarely used in practical applications, having been largely replaced by the joule and other SI units. However, it may still be referenced in historical data, legacy systems, or specific industries dealing with older measurement standards within the energy and mechanical sectors.
