Gigapascal to millibar Conversion
1 gigapascal (GPa) is equal to 10000000 millibar (mbar).
1 GPa = 10000000 mbar
or
1 mbar = 0.0000001 GPa
Formula
To convert a pressure from gigapascal (GPa) to millibar (mbar), multiply the pressure in gigapascal by 10000000
p(mbar) = p(GPa) × 10000000
Examples:
Convert 1 gigapascal to millibar:
p(mbar) = 1GPa × 10000000 = 10000000 mbar
