Inch-Pound
The inch-pound (in·lbf) is a unit of torque or energy, representing the force of one pound applied at the end of a one-inch lever arm.
History/Origin
The inch-pound has been used primarily in the United States and other countries that employ imperial units, originating from the traditional use of inches and pounds in mechanical and engineering contexts, with its formal recognition dating back to the 19th century.
Current Use
It is commonly used in engineering, automotive, and mechanical applications to measure torque and energy, especially in contexts where imperial units are standard.
Horsepower (Metric) Hour
A unit of energy representing the amount of work done by one horsepower over one hour, equivalent to 745.7 joules.
History/Origin
The horsepower hour was historically used to quantify energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.
Current Use
It is rarely used in modern practice, but may still appear in legacy systems or specific industrial applications to measure energy output or consumption related to horsepower-rated equipment.
