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
Pa = mmHg × 133.322One mmHg (millimeter of mercury) equals approximately 133.322 pascals. This conversion comes from the original mercury barometer — the pressure needed to raise a mercury column by 1 millimeter. It's used in medicine (blood pressure), physics (vacuum), and meteorology.
