Convert Gigapascals to Kilopascals (GPa to kPa)
1 gigapascal (GPa) = 1000000 kilopascals (kPa). 1 kPa = 0.000001 GPa. Example: 15 GPa = 15 × 1000000 = 15000000 kPa.

How to Convert Gigapascal to Kilopascal
- 1 GPa = 1000000 kPa
- 1 kPa = 0.000001 GPa
- Example: convert 15 GPa to kPa: 15 GPa = 15 × 1000000 kPa = 15000000 kPa
Formula
kPa = GPa × 1000000
Derivation from SI units:
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
- 1 kPa = 10³ Pa
- 1 GPa = 1000000000 Pa ÷ 1000 Pa per kPa = 1000000 kPa
Both units are defined exactly, so the factor is exact. Gigapascal definition: gigapascal; Kilopascal definition: kilopascal.
Worked examples
- A reading of 10 GPa converts to 10000000 kPa.
10 GPa × 1000000 = 10000000 kPa - A value of 190 GPa is 190000000 kPa.
190 GPa × 1000000 = 190000000 kPa

Where it's used
Gigapascals are used for young's modulus and shear modulus of metals, ceramics and composites, while kilopascals appear in tyre pressure outside the United States (about 200–250 kPa for cars). Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
