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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
Psi
Psi (pounds per square inch) is a unit of pressure measurement representing the force of one pound applied to an area of one square inch.
History/Origin
The psi originated in the United States as a customary unit of pressure, commonly used in engineering and industrial applications. It became standardized with the development of the imperial system of units.
Current Use
Psi is widely used today in various fields such as automotive tire pressure, plumbing, and industrial pressure measurements, especially in the United States and other countries using imperial units.
