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.
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.
