Newton/square Millimeter
Newton per square millimeter (N/mm²) is a unit of pressure or stress, representing the force of one newton applied over an area of one square millimeter.
History/Origin
The unit derives from the SI base unit newton for force and the millimeter for area, commonly used in engineering and material science to measure stress and pressure. It has been in use since the adoption of the SI system, with increased application in fields requiring precise measurement of high pressures.
Current Use
N/mm² is widely used in engineering, material science, and construction to specify material strength, stress, and pressure levels, especially in contexts where high precision is required, such as in the specification of tensile strength and pressure ratings.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
