1 Pascal = 0 Bar
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 = Pa ÷ 100000A 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.
