Conversion formula

Forward
millimeters of mercury = bars × 750.062
Reverse
bars = millimeters of mercury × 0.001333

Example: 10 bar × 750.062 = 7,500.62 mmHg.

About both units

From

Bar

bar

The bar equals 100,000 pascals — slightly less than one atmosphere (1.01325 bar). It is a convenient unit for everyday pressures: tyre pressures, diving depth, weather fronts. Common in European engineering.

Real-world: Car tyre: 2.0–2.5 bar. SCUBA at 10 m depth: 2 bar absolute. Fire hose: 5–7 bar.

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.

Tips & common mistakes

Quick tips

  • 1 bar = 100 kPa = 0.987 atm = 14.5 psi.
  • Almost 1 atm — convenient approximation.
  • Tyre pressures: 2.0–2.5 bar typical car, 6–10 bar truck.

Avoid these

  • Assuming 1 bar = 1 atm exactly — 1.3% off.
  • Mixing bar with psi — need factor of 14.5.
  • Using bar for high-pressure work — switch to MPa.
