Conversion formula

Forward
millimeters of mercury = pascals × 0.007501
Reverse
pascals = millimeters of mercury × 133.322

Example: 10 Pa × 0.007501 = 0.07501 mmHg.

About both units

From

Pascal

Pa

The pascal is the SI unit of pressure — one newton per square metre. Named after Blaise Pascal. 1 Pa is a very small pressure; atmospheric pressure is about 101,325 Pa. Pressure readings in engineering are usually in kPa or MPa.

Real-world: Atmospheric pressure: 101,325 Pa. Conversation level: 0.001 Pa sound pressure. Truck tyre: 900,000 Pa.

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 Pa = 1 N/m².
  • 1 kPa = 1000 Pa; 1 MPa = 1,000,000 Pa; 1 bar = 100,000 Pa.
  • Use kPa, MPa or bar for practical engineering work.

Avoid these

  • Confusing Pa with psi — 1 psi = 6895 Pa.
  • Using Pa for tyre pressures — 220,000 Pa unwieldy; use 2.2 bar.
  • Mixing Pa absolute and Pa gauge without specification.

Frequently asked questions

How many millimeters of mercury in a pascal?
