Millimeter of Mercury

mmHg

The millimetre of mercury equals about 133.3 Pa — the pressure exerted by a 1 mm column of mercury at 0 °C under standard gravity. Traditionally and still used in medicine: blood pressure of 120/80 mmHg.

Real-world: Normal blood pressure: 120/80 mmHg. Atmospheric: 760 mmHg. Good vacuum: <1 mmHg.

Megapascal

MPa

The megapascal equals 1,000,000 pascals or 10 bar. Used for high-pressure engineering — hydraulic systems, material strength, concrete compression tests. 1 MPa is roughly the pressure of a 100-tonne weight on 1 m².

Real-world: Concrete compressive strength: 20–60 MPa. Hydraulic press: 30–70 MPa. Steel yield strength: 250+ MPa.

Tips & common mistakes

Quick tips

1 mmHg ≈ 133.32 Pa ≈ 1 Torr.
760 mmHg = 1 atm.
Blood-pressure cuffs display mmHg worldwide.

Avoid these

Confusing mmHg with mmH₂O (different unit, factor of 13.6).
Mixing mmHg with torr in precise vacuum physics — they differ by one part per million.
Writing blood pressure in kPa — use mmHg for medical continuity.
