Millipascal
A millipascal (mPa) is a unit of pressure equal to one thousandth of a pascal, the SI unit of pressure.
History/Origin
The millipascal is derived from the pascal, which was named after Blaise Pascal. It is used in contexts requiring very small pressure measurements, but its usage is relatively uncommon due to the widespread adoption of the pascal.
Current Use
Millipascals are primarily used in scientific and engineering fields to measure very low pressures, such as in fluid dynamics, vacuum systems, and sensitive instrumentation within the 'Pressure' converter category of 'Common Converters'.
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.
