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 The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.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.
Nanopascal
The nanopascal (nPa) is a unit of pressure equal to one billionth of a pascal, where 1 nPa = 10^-9 Pa.
History/Origin
The nanopascal was introduced as part of the SI unit system's extension to accommodate very small pressure measurements, primarily in scientific research involving micro- and nanoscale phenomena.
Current Use
Nanopascals are used in high-precision scientific applications such as atmospheric pressure measurements, microfluidics, and nanotechnology research where extremely low pressure differences need to be quantified.
