Bars to gigapascal Conversion
1 bars (bar) is equal to 0.0001 gigapascal (GPa).
1 bar = 0.0001 GPa
or
1 GPa = 10000 bar
Formula
To convert a pressure from bars (bar) to gigapascal (GPa), divide the pressure in bars by 10000
p(GPa) = p(bar) / 10000
Examples:
Convert 100 bars to gigapascal:
p(GPa) = 100bar / 10000 = 0.01 GPa
