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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
Petapascal
A petapascal (PPa) is a unit of pressure equal to 10^15 pascals.
History/Origin
The petapascal was introduced as part of the SI prefix system to represent extremely high pressures, mainly in scientific and industrial contexts, as the need to measure such large values arose with advancements in high-pressure physics and astrophysics.
Current Use
Petapascal is used in fields such as astrophysics, geophysics, and high-pressure physics to quantify extremely high pressures, such as those found in planetary interiors or during high-energy experiments.
