Pound-Force/square Foot
Pound-force per square foot (lbf/ft^2) is a unit of pressure representing the force of one pound-force applied over an area of one square foot.
History/Origin
This unit has been traditionally used in the United States for measuring pressure, especially in fields like construction and engineering, originating from the imperial system of units.
Current Use
Today, pound-force per square foot is primarily used in specific engineering and construction contexts within the US, although it has largely been replaced by SI units like Pascals in scientific and international applications.
Ton-Force (Long)/square Inch
Ton-force per square inch (tonf/in²) is a unit of pressure representing the force exerted by one ton-force distributed over an area of one square inch.
History/Origin
The ton-force (long) originated from the imperial system of units used in the UK, where it was defined as the force exerted by a long ton (2,240 pounds) under standard gravity. It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.
Current Use
Today, ton-force per square inch is rarely used in modern engineering, having been largely replaced by pascals (Pa) or pounds per square inch (psi). It may still appear in legacy systems or specific industrial contexts in the UK.
