1 Millibar = 0.0001 Megapascal

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

MPa = mbar × 0.0001

One millibar equals 100 pascals, and one megapascal equals 1,000,000 pascals. The conversion ratio is 100 ÷ 1,000,000 = 0.0001. This conversion is rarely needed since millibar is for low pressures (atmospheric) while megapascal is for high pressures.
