Convert Gigapascals to Pascals (GPa to Pa)
1 gigapascal (GPa) = 1000000000 pascals (Pa). 1 Pa = 1 × 10⁻⁹ GPa. Example: 15 GPa = 15 × 1000000000 = 15000000000 Pa.

How to Convert Gigapascal to Pascal
- 1 GPa = 1000000000 Pa
- 1 Pa = 1 × 10⁻⁹ GPa
- Example: convert 15 GPa to Pa: 15 GPa = 15 × 1000000000 Pa = 15000000000 Pa
Formula
Pa = GPa × 1000000000
Derivation from SI units:
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
Both units are defined exactly, so the factor is exact. Gigapascal definition: gigapascal; Pascal definition: pascal.
Worked examples
- A reading of 10 GPa converts to 10000000000 Pa.
10 GPa × 1000000000 = 10000000000 Pa - A value of 190 GPa is 190000000000 Pa.
190 GPa × 1000000000 = 190000000000 Pa

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