U+03BA. The tenth Greek letter, said like the k of make. Geometry writes curvature with it and linear algebra a matrix's condition number. HTML names it κ and LaTeX \kappa; there is no Alt code.
U+039A. The capital, identical in shape to the Latin K that arose from it. Κ is its HTML name. LaTeX gives it no macro.
U+03F0. Script kappa, the cursive form of the small letter. It has its own code point because math and science use it as a separate symbol. ϰ in HTML; \varkappa in LaTeX needs the amssymb package.
U+1D705. Kappa in lowercase, italic, as formulas print a curvature or a condition number. In Greek words the letter stays U+03BA.
U+1D718. Script kappa once more, now italic: a math alphabet copy of U+03F0.
U+1D6EB. Italic capital kappa, a math alphabet letter. Its decomposition is U+039A, not the Latin K.
U+03D7. The kai sign: a kappa with one more stroke at the foot, which Greek manuscripts and signs use for the word and, much as Latin letters use &. Unicode 3.0 (1999) added it.
Made of U+03BA, U+03B1 and U+03B9. Kappa, alpha, iota: the word for and in modern Greek, spelled out. The kai sign is a short way to write it.
U+004B. The Latin K. Capital kappa is its ancestor and its double on screen, with a code point of its own: U+039A.
U+0138. Kra, a Latin letter once used to write Greenlandic. It is shaped like small kappa and stands for a different sound, q. ĸ in HTML.

How it works

κ is the kappa symbol: Greek small letter kappa, U+03BA, the tenth letter of the Greek alphabet. The rows add the capital Κ, the script form ϰ, math styles such as 𝜅, the kai sign ϗ and the look-alike ĸ.

Read the full guide

Kappa is the Greek letter for k

Kappa writes the sound k. The Latin K and the Cyrillic К arose from it, and capital kappa, U+039A, is identical in shape to the Latin K, U+004B. English often spells Greek names that have a kappa with c, as in Corinth and Crete.

κ and ϰ are two code points

ϰ, U+03F0, is script kappa, which Unicode's names list calls a technical symbol. It is the cursive shape of κ, encoded apart for use as a symbol.

  • As a Greek numeral kappa is 20, written κʹ.
  • ϗ is the kai sign, a kappa with an extra stroke that stands for the Greek word for and.
  • LaTeX has \kappa without a package; \varkappa, for ϰ, comes with amssymb.

Questions and answers

How do I type the kappa symbol?

Kappa has no Alt code, so copying is the short way. In HTML κ is the small letter and Κ the capital, κ and Κ as numbers. In LaTeX \kappa prints κ in math mode.

What does the kappa letter stand for?

Small κ is the curvature of a curve in geometry, the condition number of a matrix in linear algebra and a thermal conductivity in physics. In statistics a kappa measures how far raters agree.

Is capital kappa the same as K?

On screen, yes: the two are drawn alike. In a file they differ. Capital kappa is U+039A and the Latin K is U+004B, so a search for one does not find the other.

How do you say kappa?

English says KAP-a, with the stress on the first syllable. Greek writes the name κάππα, with a double pi.

What kappa is for, as https://en.wikipedia.org/wiki/Kappa records it: the tenth letter, the sound k, the numeral value 20, how English says the name and how Greek spells it, the Latin and Cyrillic letters that arose from it, the capital that is identical to the Latin K, Greek names written with c in English, the cursive form and why it has a code point of its own, curvature, the condition number, the kappa statistics and thermal conductivity among its uses, and the rule that styled Greek text keeps the plain letters.

Left out: the other Greek letters, the two Coptic dialect letters named kapa, the syllables of other scripts that only share the name, and the name in Greek letters, which is too long for a row.
