How to Convert GPa to Pascal

1 GPa = 1 × 109 pascals

Pascal = GPa × 1 × 109

Example: 1 GPa × 1 × 109 = 1 × 109 Pa

Reverse Conversion

To convert pascals back to gigapascals:

  • Remember, 1 pascal equals 1 × 10-9 gigapascals.
  • To convert 1 × 109 Pa to GPa, multiply 1 × 109 x 1 × 10-9, resulting in 1 GPa.

1 GPa is also equal to:

  • 1000000 kPa
  • 10000 bar
  • 145040 psi

Frequently Asked Questions

How much is 1 GPa in pascals?
