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 Foot
Pound-force per square foot (lbf/ft^2) is a unit of pressure representing the force of one pound-force applied over an area of one square foot.
History/Origin
This unit has been traditionally used in the United States for measuring pressure, especially in fields like construction and engineering, originating from the imperial system of units.
Current Use
Today, pound-force per square foot is primarily used in specific engineering and construction contexts within the US, although it has largely been replaced by SI units like Pascals in scientific and international applications.
