Convert Pascals to Gigapascals (Pa to GPa)
1 pascal (Pa) = 1 × 10⁻⁹ gigapascals (GPa). 1 GPa = 1000000000 Pa. Example: 15 Pa = 15 × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ GPa.

How to Convert Pascal to Gigapascal
- 1 Pa = 1 × 10⁻⁹ GPa
- 1 GPa = 1000000000 Pa
- Example: convert 15 Pa to GPa: 15 Pa = 15 × 1 × 10⁻⁹ GPa = 1.5 × 10⁻⁸ GPa
Formula
GPa = Pa ÷ 1000000000
Derivation from SI units:
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
Both units are defined exactly, so the factor is exact. Pascal definition: pascal; Gigapascal definition: gigapascal.
Worked examples
- A reading of 125 Pa converts to 1.25 × 10⁻⁷ GPa.
125 Pa × 1 × 10⁻⁹ = 1.25 × 10⁻⁷ GPa - A value of 1000 Pa is 0.000001 GPa.
1000 Pa × 1 × 10⁻⁹ = 0.000001 GPa

Where it's used
Pascals are used for cleanroom and isolator pressure differentials (typically 10–50 Pa), while gigapascals appear in young's modulus and shear modulus of metals, ceramics and composites. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
