PSIG to PSIA Converter

Your details

Choose whether to start from gauge pressure or absolute pressure.
Enter the pressure you want to convert. Negative values are valid for vacuum (below atmospheric) pressures.
PSI
Pick a common altitude to auto-fill the atmospheric pressure, or choose "Enter manually" to type your own value.
Local atmospheric pressure used in the conversion. Standard sea level is 14.696 PSI. Select an altitude preset above to fill this automatically.

Converted pressure (absolute or gauge)

Result in bar7.908bar
Result in kPa790.8kPa
Atmospheric pressure used14.696PSI
Input in bar6.8948bar
Input in kPa689.48kPa
Converted pressure (PSI)114.696
Atmospheric pressure (PSI)14.696

100.000 PSIG = 114.696 PSIA

  • 100.000 PSIG equals 114.696 PSIA at 14.696 PSI atmospheric pressure.
  • In bar: 7.9080 bar. In kPa: 790.80 kPa.
