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.
Petapascal
A petapascal (PPa) is a unit of pressure equal to 10^15 pascals.
History/Origin
The petapascal was introduced as part of the SI prefix system to represent extremely high pressures, mainly in scientific and industrial contexts, as the need to measure such large values arose with advancements in high-pressure physics and astrophysics.
Current Use
Petapascal is used in fields such as astrophysics, geophysics, and high-pressure physics to quantify extremely high pressures, such as those found in planetary interiors or during high-energy experiments.
