Megapascal
The megapascal (MPa) is a unit of pressure equal to one million pascals, where one pascal (Pa) is the pressure exerted by a force of one newton per square meter.
History/Origin
The megapascal was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring high pressures, especially in engineering and scientific applications, replacing larger units like the bar in many contexts.
Current Use
The MPa is widely used today in engineering, material science, and industrial applications to specify pressures in fields such as hydraulics, pneumatics, and structural engineering.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
