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.
Microbar
A microbar (µbar) is a unit of pressure equal to one millionth of a bar, where 1 bar equals 100,000 pascals.
History/Origin
The microbar was introduced as a subunit of the bar to measure very low pressures, particularly in meteorology and vacuum technology, gaining usage in the 20th century as precision pressure measurements became more common.
Current Use
Today, the microbar is used primarily in meteorology for measuring atmospheric pressure variations and in scientific research requiring precise low-pressure measurements.
