Ksi-Sqrt(inch) (ksi-sqrt(in)) is a unit in the category of Fracture toughness. It is also known as ksi square root inches, kilo force pound per square inch square root inches. Ksi-Sqrt(inch) (ksi-sqrt(in)) has a dimension of ML-0.5T-2 where M is mass, L is length, and T is time. It can be converted to the corresponding standard SI unit Pa-sqrt(m) by multiplying its value by a factor of 1098843.49012.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).

Other units in the category of Fracture toughness include MPa-Sqrt(meter) (MPa-sqrt(m)), Pa-Sqrt(meter) (Pa-sqrt(m)), and Psi-Sqrt(inch) (psi-sqrt(in)).
