Psi to Millimeters Of Mercury Converter

51.7149252

How to convert psi to millimeters of mercury

millimeters of mercury = psi × 51.7149252

To convert psi to millimeters of mercury, multiply the number of psi by 51.7149252.

1 psi = 51.7149252 mmHg

Examples

  • A typical car tire pressure: 32 psi × 51.7149252 = 1,654.87761 mmHg
  • 100 psi × 51.7149252 = 5,171.49252 mmHg

Good to know

Psi means pounds-force per square inch (lbf/in²). Gauge readings (psig) are measured relative to atmospheric pressure, absolute readings (psia) relative to a vacuum; the conversion factor is the same for both.

This is the conventional millimeter of mercury, 133.322387415 Pa. It differs from the torr (101,325/760 Pa) by less than one part in seven million, so the two are interchangeable in practice.

Unit definitions

Psi
Psi is one pound-force per square inch, about 6894.757 pascals. It is the everyday pressure unit in the United States, used for tires, compressors and plumbing.
Millimeter of mercury (mmHg)
A millimeter of mercury is the pressure exerted by a 1 mm column of mercury, conventionally 133.322387415 pascals. It is the standard unit for blood pressure readings.
