1 Kilopascal = 0.01 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 = kPa ÷ 100A bar is exactly 100 kilopascals — since 1 bar = 100,000 Pa and 1 kPa = 1000 Pa, dividing by 100 converts kPa to bar. This conversion is critical for European industrial standards, hydraulic system design, and meteorological pressure reporting. Standard atmospheric pressure is 101.325 kPa = 1.01325 bar.
