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.
Attopascal
The attopascal (aPa) is a unit of pressure equal to 10^-18 pascals, representing an extremely small pressure measurement.
History/Origin
The attopascal was introduced as part of the SI prefixes to denote very small quantities of pressure, but it is rarely used in practical applications due to its minuscule magnitude.
Current Use
The attopascal is primarily used in scientific research and theoretical contexts where extremely small pressure differences are relevant, although it remains largely a conceptual unit.
