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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
Femtopascal
The femtopascal (fPa) is a unit of pressure equal to 10^-15 pascals.
History/Origin
The femtopascal is a derived SI unit introduced as part of the International System of Units' effort to create a comprehensive set of prefixes for very small measurements, although it is rarely used in practice.
Current Use
The femtopascal is primarily used in scientific research involving extremely low pressure measurements, such as in nanotechnology and quantum physics, but it remains a theoretical unit with limited practical application.
