Kilogram-Force/sq. Millimeter
Kilogram-force per square millimeter (kgf/mm²) is a unit of pressure representing the force of one kilogram-force applied over an area of one square millimeter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, and was commonly used in engineering and material science to measure pressure before the adoption of SI units. Its usage has declined with the standardization of the pascal (Pa).
Current Use
Today, kgf/mm² is still used in some engineering fields, especially in material strength and pressure measurements, but it is largely replaced by SI units like the pascal (Pa) or megapascals (MPa).
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.
