About mmHg and Kilopascal

The millimeter of mercury is about 133.322 pascals, the height a pressure pushes a mercury column. Blood pressure worldwide is still reported in mmHg. The kilopascal is 1,000 pascals. Tire pressures in metric countries, weather systems, and engineering specs commonly use kilopascals. One mmHg equals 0.1333223684 Kilopascals (1 mmHg = 0.1333223684 kPa). mmHg is used in blood pressure readings and in medical vacuum and ventilation. Kilopascal is used in tire pressure in metric countries.

Precision and Rounding:Several pressure factors are exact by definition (1 atm = 101,325 Pa; 1 bar = 100,000 Pa) while others, like psi and mmHg, are derived and carry long decimals. Tire and weather readings tolerate whole-number rounding; calibration, medicine, and process engineering need the full factor before rounding.

Use the pressure conversion guide to compare mmHg, mbar, inHg, kPa, Pa, and torr across medical, weather, aviation, vacuum, and engineering work.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
