Formula: mmHg = Kilopascal × 7.501
Multiply any kilopascal value by 7.501 to get mmhg.
Reverse: Kilopascal = mmHg × 0.1333
Common kilopascal values — factor: 1 kPa = 7.501 mmHg

The kilopascal (kPa) equals 1,000 pascals and is the practical everyday pressure unit in metric countries. It is the standard unit for tire pressure, blood pressure, and weather maps in countries using SI.
Blood pressure in many countries is expressed in kPa (normal: ~16/10.7 kPa), though mmHg remains dominant in medicine. Car tire pressure is typically 200–250 kPa. Weather maps use hPa (= mbar) for atmospheric pressure.
Interesting fact: The 'bends' (decompression sickness) in scuba diving occurs when dissolved nitrogen forms bubbles as pressure drops — a drop of just a few kPa too quickly can be fatal.
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.
Converting kilopascal to mmhg 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 kPa = 37.5 mmHg and 10 kPa = 75.01 mmHg. For the reverse: 1 mmHg = 0.1333 kPa. The exact factor is 1 kPa = 7.501 mmHg.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
