Millimeter Water (4°c)
Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.
History/Origin
The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.
Current Use
It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.
Ton-Force (Short)/sq. Foot
Ton-force per square foot (tonf/ft²) is a unit of pressure representing the force exerted by one ton-force distributed over an area of one square foot.
History/Origin
The ton-force per square foot originated from the use of the ton-force as a unit of force in the Imperial system, primarily in engineering and construction contexts, to measure pressure or stress levels. Its usage has declined with the adoption of SI units but remains relevant in specific industries.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units such as pascals. It may still be encountered in legacy systems or specific regional applications related to structural and material stress assessments.
