Megapascals to pounds per square inch
Type a value in MPa to get it in psi instantly.
29,007.55psi
That's 20× as stiff as rubber, while wood is 65× stiffer. A 1 m bar of 1 cm² under 100 kg would stretch about 49.05 mm.
Convert the other way: psi to MPa
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 MPa to psi
To convert megapascals to pounds per square inch, multiply by 145.038.
Example: 200 MPa × 145.038 = 29,007.5 psi.
In the other direction, 1 psi = 0.00689476 MPa.
