Megapascal root meter to ksi root inch
Type a value in MPa·√m to get it in ksi·√in instantly.
45.5ksi·√in
That's 1.67× as tough as aluminum alloy, while structural steel is 2× tougher. At 200 MPa of stress, a crack about 19.89 mm long would become critical.
Convert the other way: ksi·√in to MPa·√m
What it means
How tough is that?
This is plane-strain toughness, K_IC, which is the worst case for a thick section. Thin sheet tolerates more.
The math
How to convert MPa·√m to ksi·√in
To convert megapascal root meter to ksi root inch, multiply by 0.910048.
Example: 50 MPa·√m × 0.910048 = 45.5024 ksi·√in.
In the other direction, 1 ksi·√in = 1.09884 MPa·√m.
