Pound-Force Inch
Pound-force inch (lbf·in) is a unit of torque representing the torque resulting from a one-pound-force applied at a perpendicular distance of one inch from the pivot point.
History/Origin
The pound-force inch has been used historically in engineering and mechanical contexts to quantify torque, especially in the United States, based on the imperial system of units. It originated from the need to measure rotational force in machinery and automotive applications.
Current Use
Today, pound-force inch is still used in engineering, automotive, and mechanical fields to specify torque values, particularly in the United States. It is often converted to SI units like newton-meters for international standardization.
Ton-Hour (Refrigeration)
A ton-hour (ton*h) is a unit of energy representing the amount of cooling provided by one ton of refrigeration over one hour.
History/Origin
The ton-hour originated from the refrigeration industry, where the 'ton' is a unit of cooling capacity, and the hour indicates the duration. It has been used historically to quantify cooling energy consumption and capacity.
Current Use
Today, the ton-hour is used in HVAC and refrigeration systems to measure cooling energy consumption, system capacity, and performance over specific periods.
