Atmospheres to gigapascal Conversion
1 atmospheres (atm) is equal to 0.000101325 gigapascal (GPa).
1 atm = 0.000101325 GPa
or
1 GPa = 9869.232667 atm
Formula
To convert a pressure from atmospheres (atm) to gigapascal (GPa), divide the pressure in atmospheres by 9869.232667
p(GPa) = p(atm) / 9869.232667
Examples:
Convert 10 atmospheres to gigapascal:
p(GPa) = 10atm / 9869.232667 = 0.00101325 GPa
