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 GPa to ksi
To convert gigapascals to kilopounds per square inch, multiply by 145.038.
Example: 200 GPa × 145.038 = 29,007.5 ksi.
In the other direction, 1 ksi = 0.00689476 GPa.
