Micropascal
The micropascal (µPa) is a unit of pressure equal to one millionth of a pascal, used to measure very low pressures.
History/Origin
The micropascal was introduced as part of the SI unit system to quantify extremely small pressure values, especially in scientific and engineering contexts, though it is rarely used in practical applications.
Current Use
The micropascal is primarily used in scientific research, acoustics, and environmental monitoring where precise measurement of very low pressures is required.
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.
