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.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter.
History/Origin
Named after Blaise Pascal, the pascal was adopted as the SI unit of pressure in 1971, replacing earlier units like the bar and atmosphere.
Current Use
The pascal is widely used in science, engineering, and meteorology to measure pressure, with common applications including atmospheric pressure, tire pressure, and fluid pressure in systems.
