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.
Millimeter Mercury (0°c)
Millimeter mercury (0°C), abbreviated as mmHg, is a unit of pressure measurement based on the height of a column of mercury in millimeters at 0°C under standard gravity.
History/Origin
The mmHg originated from the use of mercury barometers in the 17th century to measure atmospheric pressure. It became a standard unit in meteorology and medicine for measuring blood pressure and other pressure-related phenomena.
Current Use
Today, mmHg is primarily used in medicine to measure blood pressure and in meteorology for atmospheric pressure readings. It is also used in various scientific and industrial applications where precise pressure measurements are required.
