Gigapascal to bars Conversion
1 gigapascal (GPa) is equal to 10000 bars (bar).
1 GPa = 10000 bar
or
1 bar = 0.0001 GPa
Formula
To convert a pressure from gigapascal (GPa) to bars (bar), multiply the pressure in gigapascal by 10000
p(bar) = p(GPa) × 10000
Examples:
Convert 2 gigapascal to bars:
p(bar) = 2GPa × 10000 = 20000 bar
