Poundal/square Foot
The poundal per square foot (pdl/ft^2) is a unit of pressure representing the force of one poundal applied over an area of one square foot.
History/Origin
The poundal is an imperial unit of force introduced in the 19th century as part of the foot-pound-second system, primarily used in engineering contexts. The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.
Current Use
The poundal per square foot is rarely used in modern practice, having been largely replaced by the pascal (Pa) in scientific and engineering applications. It may still appear in legacy systems or specific regional engineering contexts.
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.
