Centimeter Mercury (0°c)
Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.
History/Origin
The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.
Current Use
Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
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.
