Convert Kilopascals to Gigapascals (kPa to GPa)
1 kilopascal (kPa) = 0.000001 gigapascals (GPa). 1 GPa = 1000000 kPa. Example: 15 kPa = 15 × 0.000001 = 0.000015 GPa.

How to Convert Kilopascal to Gigapascal
- 1 kPa = 0.000001 GPa
- 1 GPa = 1000000 kPa
- Example: convert 15 kPa to GPa: 15 kPa = 15 × 0.000001 GPa = 0.000015 GPa
Formula
GPa = kPa ÷ 1000000
Derivation from SI units:
- 1 kPa = 10³ Pa
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
- 1 kPa = 1000 Pa ÷ 1000000000 Pa per GPa = 0.000001 GPa
Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; Gigapascal definition: gigapascal.
Worked examples
- A reading of 20 kPa converts to 0.00002 GPa.
20 kPa × 0.000001 = 0.00002 GPa - A value of 300 kPa is 0.0003 GPa.
300 kPa × 0.000001 = 0.0003 GPa

Where it's used
Kilopascals are used for tyre pressure outside the United States (about 200–250 kPa for cars), 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.

Frequently asked questions
How many gigapascals are in 1 kilopascal?
1 kPa = 0.000001 GPa.
How do I convert kilopascals to gigapascals?
Multiply the value in kPa by 0.000001, or divide it by 1000000. For example, 15 kPa × 0.000001 = 0.000015 GPa.
Is the kPa to GPa conversion exact?
Yes. Both units are defined exactly, and 1 kPa is exactly 0.000001 GPa.
