Pounds per square inch to megapascals
Type a value in psi to get it in MPa instantly.
1.379MPa
Nothing on our list is smaller: rubber is 7.3× stiffer. A 1 m bar of 1 cm² under 100 kg would stretch about 7,114 mm.
Convert the other way: MPa to psi
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 psi to MPa
To convert pounds per square inch to megapascals, multiply by 0.00689476.
Example: 200 psi × 0.00689476 = 1.37895 MPa.
In the other direction, 1 MPa = 145.038 psi.
