Psi
Psi (pounds per square inch) is a unit of pressure measurement representing the force of one pound applied to an area of one square inch.
History/Origin
The psi originated in the United States as a customary unit of pressure, commonly used in engineering and industrial applications. It became standardized with the development of the imperial system of units.
Current Use
Psi is widely used today in various fields such as automotive tire pressure, plumbing, and industrial pressure measurements, especially in the United States and other countries using imperial units.
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.
