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.
Exapascal
An exapascal (EPa) is a unit of pressure equal to 10^18 pascals, used to measure extremely high pressures.
History/Origin
The exapascal was introduced as part of the International System of Units (SI) prefixes to represent very large pressure values, primarily in scientific and engineering contexts involving high-pressure phenomena.
Current Use
The exapascal is mainly used in fields such as geophysics, astrophysics, and high-pressure physics to describe immense pressures found in planetary interiors, stellar environments, and experimental high-pressure research.
