Symbol
- In graph theory, the connectivity of a graph is given by κ.
- In differential geometry, the curvature of a curve is given by κ.
- In physics, the torsional constant of an oscillator is given by κ as well as Einstein constant of gravitation.
- In structural engineering, κ is the ratio of the smaller factored moment to the larger factored moment and is used to calculate the critical elastic moment of an unbraced steel member.
- In electrical engineering, κ is the multiplication factor, a function of the R/X ratio of the equivalent power system network, which is used in calculating the peak short-circuit current of a system fault. κ is also used to notate conductivity, the reciprocal of resistivity, rho.
- In chemistry, the compressibility of a compound is given by κ.
- In psychology and psychiatry, kappa represents a measure of diagnostic reliability.
- In biology, kappa and kappa prime are important nucleotide motifs for a tertiary interaction of group II introns.
- In biology, kappa designates a subtype of an antibody component.
- In pharmacology, kappa represents a type of opioid receptor.
- Kappa statistics such as Cohen's kappa and Fleiss' kappa are methods for calculating inter-rater reliability.
Upper-case letter Κ is used as a symbol for:
