How to convert millimeters of mercury to kilopascals

kilopascals = millimeters of mercury ÷ 7.50061576

To convert millimeters of mercury to kilopascals, divide the number of millimeters of mercury by 7.50061576.

1 mmHg = 0.133322387 kPa

Examples

  • 120 mmHg ÷ 7.50061576 = 15.9986865 kPa
  • Approximately standard atmospheric pressure: 760 mmHg ÷ 7.50061576 = 101.325014 kPa

Good to know

Blood pressure is recorded in mmHg in most countries and in kPa in a few. A reading of 120 mmHg is about 16 kPa.

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

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.
Kilopascal (kPa)
A kilopascal is 1000 pascals. It is the common SI unit for tire pressures, weather reports and engineering in metric countries.
