Pound-Force/square Inch
Pound-force per square inch (lbf/in^2) is a unit of pressure representing the force of one pound-force applied over an area of one square inch.
History/Origin
The unit originated from the Imperial system and became widely used in the United States for measuring pressure, especially in engineering and tire pressure contexts.
Current Use
Today, lbf/in^2, commonly known as psi, is still used in various fields such as automotive, aerospace, and industrial applications to measure pressure.
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.
