How to Convert Pascal to GPa

1 pascal = 1 × 10-9 gigapascals

GPa = Pascal × 1 × 10-9

Example: 643 Pa × 1 × 10-9 = 6.43 × 10-7 GPa

Reverse Conversion

To convert gigapascals back to pascals:

  • Remember, 1 GPa equals 1 × 109 pascals.
  • To convert 6.43 × 10-7 GPa to Pa, multiply 6.43 × 10-7 x 1 × 109, resulting in 643 Pa.

643 Pa is also equal to:

  • 0.643 kPa
  • 0.00643 bar
  • 0.093259 psi
