Formula: Inch Hg = kgf/cm² × 28.96
Multiply any kgf/cm² value by 28.96 to get inch hg.
Reverse: kgf/cm² = Inch Hg × 0.03453

Kilograms-force per square centimeter (kgf/cm²) is a traditional metric pressure unit that was widely used in continental Europe and Asia before SI standardization. One kgf/cm² equals approximately 98,066.5 Pa or 0.981 bar.
kgf/cm² remains common in older Japanese, Russian, Chinese, and Indian engineering standards for boiler pressure, hydraulic systems, and material strength specifications. Many legacy industrial gauges still read in kgf/cm².
Interesting fact: 1 kgf/cm² is nearly identical to 1 atm (ratio: 0.968), which is why it was historically used as a convenient engineering approximation for atmospheric pressure in many countries.
Inches of mercury (inHg) is the pressure unit used in US aviation and weather reporting, defined as the pressure exerted by a 1-inch column of mercury (3,386.39 Pa). It has been standard in US aviation since the early 20th century.
US aviation altimeters are set in inHg (standard: 29.92 inHg). US weather broadcasts report barometric pressure in inHg. HVAC engineers in the US use inHg for duct static pressure measurements.
Interesting fact: Pilots set their altimeter to the local QNH (pressure at sea level) in inHg to ensure their altitude reading is accurate — a difference of 0.1 inHg causes an altimeter error of about 100 feet.
Converting kgf/cm² to inch hg is a common task in engineering, medicine, meteorology, and science. Different industries and countries use different pressure units — PSI in the US, bar in Europe, mmHg in medicine, and pascals in physics — making accurate conversion essential for cross-disciplinary work.
Quick reference: 5 kgf/cm² = 144.8 inHg and 10 kgf/cm² = 289.6 inHg. For the reverse: 1 inHg = 0.03453 kgf/cm². The exact factor is 1 kgf/cm² = 28.96 inHg.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
