1 Millibar = 0.1 Kilopascal

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

kPa = mbar × 0.1

One millibar equals 100 pascals, and one kilopascal equals 1000 pascals. The conversion ratio is 100 ÷ 1000 = 0.1. This simple conversion (divide by 10) appears frequently when converting weather reports to SI units.
