What does 1 gigapascal represent?

1 gigapascal (GPa) is a unit of pressure equal to one billion pascals (N/m²), commonly used to express very high pressures in engineering and materials science.

Psi (pound per square inch) measures pressure based on one pound-force applied to an area of one square inch, used primarily in Imperial and US customary systems.

Why convert from GPa to psi?

Converting from GPa to psi helps translate high-pressure scientific measurements into practical units used in industrial, automotive, and hydraulic applications.
