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.
Inch Water (60°f)
Inch water (60°F), symbol inAq, is a unit of pressure measuring the height of a water column at 60°F that exerts a pressure equivalent to one inch of water column.
History/Origin
The inch water unit originated in the United States as a practical measurement for low-pressure applications, particularly in HVAC and fluid systems, based on the height of a water column. Its use has been standardized in various industries for measuring small pressure differences.
Current Use
It is currently used in fields such as HVAC, pneumatic systems, and low-pressure fluid measurements to quantify small pressure differences, especially in the United States.
