1 Kilopascal = 10 Millibar
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
mbar = kPa × 10A kilopascal equals 10 millibars — since 1 kPa = 1000 Pa and 1 mbar = 100 Pa, then 1000 ÷ 100 = 10. Meteorologists use hPa (hectopascals, equivalent to mbar) for atmospheric pressure. Standard sea-level pressure is 1013.25 hPa/mbar = 101.325 kPa.
