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 The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.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.
Inch Mercury (60°f)
Inch of mercury (60°F) is a unit of pressure measurement representing the height of a column of mercury 1 inch high at 60°F under standard gravity.
History/Origin
Originally used in barometry and meteorology, the inch of mercury has been a standard unit for measuring atmospheric pressure in the Imperial system since the 19th century.
Current Use
It is still used in some regions, such as the United States, primarily for measuring atmospheric pressure in weather reports and aviation, although it is gradually being replaced by Pascals in scientific contexts.
