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
kPa = atm × 101.325One atmosphere equals 101,325 pascals, which equals 101.325 kilopascals. This conversion is common in meteorology (replacing millibars), aviation, and engineering where SI units are preferred over imperial.
