Compared to Pa and even PSI, GPa is a really big unit of pressure. We will show you how to convert GPa to PSI (gigapascals to pounds per square inch). You can do it manually, or use our GPa to PSI calculator (insert GPa, get PSI) and GPa to PSI conversion chart with 0.0001 GPa to 10,000 GPa converted into PSI.
Namely, it is important that we understand what we are converting here:
- GPa or GigaPascal is a unit of pressure equal to 1,000,000,000 Pa (that’s a billion Pascals). Pa or Pascal is the basic SI unit for measuring pressure, equal to 1 Newton of force being applied to 1 square meter of surface area. GPa or billion of Pascals in a much larger unit than PSI.
- PSI or Pounds per Square Inch is a US and UK unit of pressure. It is equal to 1 pound-force being applied to 1 square inch of surface area. Compared to GPa, PSI is a much smaller unit.
How to convert GPa to PSI?
You just need to know how many PSI is 1 GPa. Here is the conversion rule:
1 GPa = 145,038 PSI
As you can see, 1 GPa is equal to 145,038 PSI. A good approximation is that 1 gigapascal is equal to about 150,000 pounds per square inch (PSI). To calculate PSI from GPa, you only need to multiply PSI by a factor of 145,038.
Example: How many PSI is 7 GPA? Here is how you can convert that:
145,038 × 7 GPa = 1,015,266 PSI
In short, 7 GPa is equal to more than a million PSI.
To help with the calculations (better option than a pocket calculator), you can use this automated GPa to PSI calculator, alongside the conversion chart found below the calculator:

If you want to convert say 18 GPa to PSI, just insert ’18’ in the calculator and you get the result: 18 GPa pressure is equal to 2,610,684 PSI.
Here is the conversion table for matching GPa and PSI pressures:
