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 The unit pdl/ft^2 was used historically in mechanical and civil engineering to measure pressure but has largely been replaced by SI units.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.
Centimeter Water (4°c)
Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.
History/Origin
The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.
Current Use
It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.
