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.
Pound-Force Foot
The pound-force foot (lbf·ft) is a unit of torque or moment of force, representing the force of one pound-force applied at a perpendicular distance of one foot from the pivot point.
History/Origin
The pound-force foot originated from the Imperial system of units, primarily used in the United States, to quantify torque in mechanical and engineering contexts before the widespread adoption of the SI system.
Current Use
Today, the pound-force foot is still used in certain engineering fields, particularly in the United States, to measure torque in automotive, mechanical, and structural applications, although the SI unit newton meter is more common internationally.
