Millimeter of Mercury (mmHg)

The millimeter of mercury is a unit of pressure based on the pressure exerted by a 1 mm tall column of mercury at 0°C. It’s the standard unit for blood pressure measurement worldwide.

Characteristics

  • Medical standard: blood pressure readings (e.g., 120/80 mmHg)
  • Standard atmosphere: exactly 760 mmHg at sea level
  • Equivalent to: 1 Torr (within 0.000015%)
  • 1 mmHg = 133.322 Pa
  • Based on: mercury column height at 0°C

Applications

  • Blood pressure measurement (sphygmomanometry)
  • Medical vacuum and respiratory equipment
  • Scientific pressure measurements
  • Cardiovascular physiology

Conversions

  • 1 mmHg = 0.133322 kPa
  • 1 mmHg ≈ 1 Torr (technically 1 Torr = 1/760 atm)
  • 1 mmHg = 0.00131579 atm
  • 1 mmHg = 0.0193368 psi
  • 760 mmHg = 1 atm (standard atmosphere)
