Kilopounds per square inch to gigapascals
Type a value in ksi to get it in GPa instantly.
1.379GPa
That's 138× as stiff as rubber, while wood is 9.4× stiffer. A 1 m bar of 1 cm² under 100 kg would stretch about 7.114 mm.
Convert the other way: GPa to ksi
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 ksi to GPa
To convert kilopounds per square inch to gigapascals, multiply by 0.00689476.
Example: 200 ksi × 0.00689476 = 1.37895 GPa.
In the other direction, 1 GPa = 145.038 ksi.
