How to Convert GPa to Pascal

1 GPa = 1 × 109 pascals

Pascal = GPa × 1 × 109

Example: 399 GPa × 1 × 109 = 3.99 × 1011 Pa

Reverse Conversion

To convert pascals back to gigapascals:

  • Remember, 1 pascal equals 1 × 10-9 gigapascals.
  • To convert 3.99 × 1011 Pa to GPa, multiply 3.99 × 1011 x 1 × 10-9, resulting in 399 GPa.

399 GPa is also equal to:

  • 3.99 × 108 kPa
  • 3990000 bar
  • 5.787 × 107 psi
