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
bar = mmHg × 0.001333224One millimeter of mercury equals 0.001333224 bar. This conversion connects medical pressure measurements (blood pressure in mmHg) with European industrial standards (bar). Since 760 mmHg = 1 atm = 1.01325 bar, this relationship is fundamental to understanding pressure across medical, scientific, and industrial contexts worldwide.
