Inch Water (4°c)
Inch water (4°C) is a unit of pressure measurement representing the pressure exerted by a one-inch column of water at 4 degrees Celsius.
History/Origin
The inch water (4°C) has been used historically in engineering and meteorology to measure low-pressure differences, especially in ventilation and HVAC systems, as a practical alternative to more complex units.
Current Use
Today, inch water (4°C) is primarily used in the United States for measuring low-pressure differences in HVAC, ventilation, and fluid systems, serving as a standard unit in these fields within the pressure converter category of common converters.
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).
