Inch Mercury (60°f)
Inch of mercury (60°F) is a unit of pressure measurement representing the height of a column of mercury 1 inch high at 60°F under standard gravity.
History/Origin
Originally used in barometry and meteorology, the inch of mercury has been a standard unit for measuring atmospheric pressure in the Imperial system since the 19th century.
Current Use
It is still used in some regions, such as the United States, primarily for measuring atmospheric pressure in weather reports and aviation, although it is gradually being replaced by Pascals in scientific contexts.
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.
