How to convert millimeters of mercury to psi

psi = millimeters of mercury ÷ 51.7149252

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

1 mmHg = 0.0193367775 psi

Examples

  • 120 mmHg ÷ 51.7149252 = 2.3204133 psi
  • Approximately standard atmospheric pressure: 760 mmHg ÷ 51.7149252 = 14.6959509 psi

Good to know

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.

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.

Unit definitions

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.
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.
