Key Formulas

Pound per Sq. Inch → Bar

bar = psi × 0.0689476

Bar → Pound per Sq. Inch

psi = bar × 14.5038

Atmosphere → Pound per Sq. Inch

psi = atm × 14.6959

Pound per Sq. Inch → Atmosphere

atm = psi × 0.068046

Formula

bar = Pa ÷ 100000

A bar is 100,000 pascals — slightly less than standard atmospheric pressure (1 atm = 1.01325 bar). The bar is widely used in Europe for pressure measurement, especially in meteorology (millibars) and industrial applications. 1 bar ≈ 14.5 psi, making it useful for comparing metric and imperial pressure scales.
