Gigapascal
A gigapascal (GPa) is a unit of pressure equal to one billion pascals, where one pascal (Pa) is the force of one newton per square meter.
History/Origin
The gigapascal was introduced as part of the International System of Units (SI) to measure high-pressure phenomena, especially in materials science and geophysics, as a larger unit than the pascal for convenience.
Current Use
GPa is commonly used to quantify stress, pressure in geological formations, material strength, and high-pressure physics applications.
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.
