Multiply any mmhg value by 0.00136 to get kgf/cm².
Reverse: mmHg = kgf/cm² × 735.6

Millimeters of mercury (mmHg) is the traditional medical pressure unit, defined as the pressure exerted by a 1 mm column of mercury at 0°C under standard gravity. It equals 133.322 Pa and is numerically identical to the torr.
Blood pressure is universally measured in mmHg worldwide: normal blood pressure is about 120/80 mmHg. Intraocular pressure (glaucoma screening) is measured in mmHg. Gas partial pressures in physiology are quoted in mmHg.
Interesting fact: The sphygmomanometer (blood pressure cuff) still uses mmHg more than 130 years after its invention, making mmHg one of the most clinically important pressure units despite not being an SI unit.
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.
Converting mmhg to kgf/cm² 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 mmHg = 0.006798 kgf/cm² and 10 mmHg = 0.0136 kgf/cm². For the reverse: 1 kgf/cm² = 735.6 mmHg. The exact factor is 1 mmHg = 0.00136 kgf/cm².
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
