The pressure of 20 gpa equals 2900 psi.
Converting 20 gpa (gigapascals) to psi (pounds per square inch) involves multiplying the gpa value by 145.038, as 1 gpa equals 145.038 psi. This conversion makes sense because both units measure pressure, but in different measurement systems, so we need to translate between them accurately.
Conversion Result
The result of converting 20 gpa to psi is approximately 2900.76 psi.

Conversion Formula
The formula to convert gpa to psi is: psi = gpa × 145.038. This works because 1 gigapascal equals 145.038 pounds per square inch, so multiplying the gpa value by this factor gives the pressure in psi. For example, converting 20 gpa: 20 × 145.038 = 2900.76 psi.
