mmHg to Pascal Conversion Formula
To convert millimeters of mercury to pascals, multiply the mmHg value by 133.322. One conventional mmHg is the pressure of a 1-millimeter mercury column, and 760 mmHg make one standard atmosphere (101,324.7 Pa).
mmHg and Pascal Explained
mmHg (mmhg)
The millimeter of mercury (mmHg) is a pressure unit representing the push of a one-millimeter column of mercury — effectively 133.322 pascals in the conventional definition. Medicine built its entire vocabulary around it: blood pressure records as 120/80 mmHg, cerebrospinal and venous pressures chart in single digits, and cerebrovascular thresholds are quoted in tens. Barometry historically read weather in hundreds, with 760 mmHg marking standard sea-level air. Despite mercury devices fading from wards, the unit survives on every digital monitor display.
Where it is used: mmHg dominates clinical medicine worldwide for blood pressure and body-cavity pressures, and it lingers in vacuum work and historic meteorological records.
Origin: Evangelista Torricelli demonstrated the mercury barometer in 1643, and reading its column height in millimeters became the standard way to express pressure for three centuries.
Pascal (pa)
The pascal (Pa) is the SI unit of pressure — one newton of force over one square meter — and the formal replacement for mercury-column measurements. Physiological pressures translate to thousands of pascals: diastolic 80 mmHg is 10,665.8 Pa and a full atmosphere is 101,325 Pa. Regulatory filings and device datasheets typically prefer its kilopascal multiple, making blood pressure 16.0 kPa at the classic 120 mmHg mark. The pascal ties pressure readings directly to newtons, meters, and seconds in any computation.
Where it is used: Pascals are required in SI documentation for medical device certification, laboratory instrumentation, and scientific publishing.
Origin: Adopted into the SI in 1971 and named for Blaise Pascal, the unit formalized pressure in mechanical terms as mercury-column instrumentation retired.

Expert Tips for mmHg to Pascal Conversion
Memorize the clinical anchors: 80 mmHg = 10.7 kPa, 120 mmHg = 16.0 kPa, 180 mmHg = 24.0 kPa — the diastolic, systolic, and severe-hypertension marks
The full column: 760 mmHg = 101,324.7 Pa, within 0.3 Pa of the 101,325 Pa standard atmosphere — a handy cross-check that your factor is right
For kilopascal output just divide the pascal result by 1,000, or multiply mmHg directly by 0.133322 — 140 mmHg becomes 18.7 kPa
High-altitude physiology: Everest-summit air pressure near 253 mmHg equals 33,730 Pa (33.7 kPa), roughly one-third of sea level
When auditing device logs remember the near-equivalence with torr (133.322 Pa) — vacuum instruments labeled in torr can be read as mmHg for every practical purpose
