Megapascal root meter to kgf per mm to the 1.5
Type a value in MPa·√m to get it in kgf/mm^1.5 instantly.
161.2kgf/mm^1.5
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.
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 kgf/mm^1.5
To convert megapascal root meter to kgf per mm to the 1.5, multiply by 3.22463.
Example: 50 MPa·√m × 3.22463 = 161.231 kgf/mm^1.5.
In the other direction, 1 kgf/mm^1.5 = 0.310114 MPa·√m.
