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
MPa = psi × 0.006894757Pound per Sq. Inch and Megapascal measure pressure (force per unit area). Pound per Sq. Inch is used in tire and pressure gauges, while Megapascal is standard in standard use. Conversion matters when checking tire pressures, weather data, or engineering specifications.
