Convert Megapascals to Gigapascals (MPa to GPa)
1 megapascal (MPa) = 0.001 gigapascals (GPa). 1 GPa = 1000 MPa. Example: 210000 MPa = 210000 × 0.001 = 210 GPa.

How to Convert Megapascal to Gigapascal
- 1 MPa = 0.001 GPa
- 1 GPa = 1000 MPa
- Example: convert 210000 MPa to GPa: 210000 MPa = 210000 × 0.001 GPa = 210 GPa
Formula
GPa = MPa ÷ 1000
Derivation from SI units:
- 1 MPa = 10⁶ Pa = 1 N/mm²
- 1 GPa = 10⁹ Pa = 1000 MPa = 1 kN/mm²
- 1 MPa = 1000000 Pa ÷ 1000000000 Pa per GPa = 0.001 GPa
Both units are defined exactly, so the factor is exact. Megapascal definition: megapascal; Gigapascal definition: gigapascal.
Worked examples
- A Young's modulus of 210000 MPa is 210 GPa.
210000 MPa × 0.001 = 210 GPa - A carbon fibre tensile strength of 3500 MPa is 3.5 GPa.
3500 MPa × 0.001 = 3.5 GPa

Frequently asked questions
Why is Young's modulus given in GPa?
Moduli of metals and ceramics are 10⁴–10⁶ MPa, so GPa gives short numbers: steel about 200, aluminium about 70.
How many gigapascals are in 1 megapascal?
1 MPa = 0.001 GPa.
How do I convert megapascals to gigapascals?
Multiply the value in MPa by 0.001, or divide it by 1000. For example, 210000 MPa × 0.001 = 210 GPa.
Is the MPa to GPa conversion exact?
Yes. Both units are defined exactly, and 1 MPa is exactly 0.001 GPa.
