Millipascal
A millipascal (mPa) is a unit of pressure equal to one thousandth of a pascal, the SI unit of pressure.
History/Origin
The millipascal is derived from the pascal, which was named after Blaise Pascal. It is used in contexts requiring very small pressure measurements, but its usage is relatively uncommon due to the widespread adoption of the pascal.
Current Use
Millipascals are primarily used in scientific and engineering fields to measure very low pressures, such as in fluid dynamics, vacuum systems, and sensitive instrumentation within the 'Pressure' converter category of 'Common Converters'.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
