Key Formulas
Pound per Sq. Inch → Bar
bar = psi × 0.0689476Bar → Pound per Sq. Inch
psi = bar × 14.5038Atmosphere → Pound per Sq. Inch
psi = atm × 14.6959Pound per Sq. Inch → Atmosphere
atm = psi × 0.068046Formula
mmHg = Pa ÷ 133.322A millimeter of mercury (mmHg) is the pressure exerted by 1 mm of mercury at 0°C — equivalent to 1 torr. Medical blood pressure is measured in mmHg (120/80 mmHg). Barometers, sphygmomanometers, and vacuum gauges historically used mercury columns, giving us this unit.
