Please provide values below to convert kilogram-force/sq. millimeter [kgf/mm^2] to inch mercury (32°F) [inHg], or Convert inch mercury (32°F) to kilogram-force/sq. millimeter.
How to Convert Kilogram-Force/sq. Millimeter to Inch Mercury (32°f)
1 kgf/mm^2 = 2895.90210768012 inHg
Example: convert 15 kgf/mm^2 to inHg:
15 kgf/mm^2 = 15 × 2895.90210768012 inHg = 43438.5316152017 inHg

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 Mercury (32°f)
Inch of mercury at 32°F (inHg) is a unit of pressure measurement representing the height of a mercury column in inches, used primarily in meteorology and aviation.
History/Origin
The inch of mercury originated from barometric pressure measurements using a mercury barometer, with its use dating back to the 18th century. It became a standard unit in weather reporting and altitude measurement.
Current Use
Today, inHg is primarily used in meteorology to report atmospheric pressure, especially in the United States, and in aviation for altitude and pressure readings.
