Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
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 The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.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.
