Gigapascal
A gigapascal (GPa) is a unit of pressure equal to one billion pascals, where one pascal (Pa) is the force of one newton per square meter.
History/Origin
The gigapascal was introduced as part of the International System of Units (SI) to measure high-pressure phenomena, especially in materials science and geophysics, as a larger unit than the pascal for convenience.
Current Use
GPa is commonly used to quantify stress, pressure in geological formations, material strength, and high-pressure physics applications.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
