About mmHg and Pascal

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 pascal is the SI derived unit of pressure: one newton per square meter. It is small for everyday pressures, so kilopascals and hectopascals appear more often in practice. One mmHg equals 133.3223684 Pascals (1 mmHg = 133.3223684 Pa). mmHg is used in blood pressure readings and in medical vacuum and ventilation. Pascal is used in physics and engineering calculations.

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).
