1. What is GPA to PSI Conversion?

GPA (Gigapascal) and PSI (Pounds per Square Inch) are both units of pressure. The conversion between these units is important in various engineering and scientific applications where different measurement systems are used.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPA \) — Pressure in Gigapascals
• \( PSI \) — Result in Pounds per Square Inch
• \( 145037.738 \) — Conversion factor from GPa to PSI

Explanation: 1 Gigapascal equals exactly 145,037.738 pounds per square inch. This conversion factor comes from the relationship between metric and imperial units of pressure.

3. Importance of Pressure Unit Conversion

Details: Accurate pressure conversion is crucial in engineering, material science, and various industrial applications where specifications may use different measurement systems.

4. Using the Calculator

Tips: Enter the pressure value in Gigapascals (GPa). The value must be positive. The calculator will automatically compute the equivalent value in PSI.
