Poundal/square Foot
The poundal per square foot (pdl/ft^2) is a unit of pressure representing the force of one poundal applied over an area of one square foot.
History/Origin
The poundal is an imperial unit of force introduced in the 19th century as part of the foot-pound-second system, primarily used in engineering contexts. The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.
Current Use
The poundal per square foot is rarely used in modern practice, having been largely replaced by the pascal (Pa) in scientific and engineering applications. It may still appear in legacy systems or specific regional engineering contexts.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
