Million psi to gigapascals
Type a value in Mpsi to get it in GPa instantly.
1,378.951GPa
That's 1.31× as stiff as diamond — nothing on our list beats it. A 1 m bar of 1 cm² under 100 kg would stretch about 0.007114 mm.
Convert the other way: GPa to Mpsi
What it means
How stiff is that?
Modulus is stiffness, not strength. A stiff material can still be brittle, and a flexible one can be very hard to break.
The math
How to convert Mpsi to GPa
To convert million psi to gigapascals, multiply by 6.89476.
Example: 200 Mpsi × 6.89476 = 1,378.95 GPa.
In the other direction, 1 GPa = 0.145038 Mpsi.
