Kilogram-Force/square Meter
Kilogram-force per square meter (kgf/m^2) is a unit of pressure representing the force of one kilogram-force applied over an area of one square meter.
History/Origin
The unit originated from the use of kilogram-force, a gravitational force unit based on the kilogram, before the adoption of SI units. It was commonly used in engineering and physics to measure pressure in contexts where gravitational force was considered.
Current Use
Today, kgf/m^2 is largely obsolete and replaced by the SI unit Pascal (Pa). However, it may still be encountered in legacy systems or specific regional applications related to pressure measurement.
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.
