How to Convert Pascal to GPa

1 pascal = 1 × 10-9 gigapascals

GPa = Pascal × 1 × 10-9

Example: 990 Pa × 1 × 10-9 = 9.9 × 10-7 GPa

Reverse Conversion

To convert gigapascals back to pascals:

  • Remember, 1 GPa equals 1 × 109 pascals.
  • To convert 9.9 × 10-7 GPa to Pa, multiply 9.9 × 10-7 x 1 × 109, resulting in 990 Pa.

990 Pa is also equal to:

  • 0.99 kPa
  • 0.0099 bar
  • 0.14359 psi

Frequently Asked Questions

How much is 990 pascals in gigapascals?
