	U+03C7. Twenty-second in the Greek alphabet. Modern Greek says it like the ch of Bach or, before e and i, like the h of human. Statistics squares it for the chi-squared test. No Alt code types it; HTML has χ and LaTeX \chi.

How it works

χ is the chi symbol: Greek small letter chi, U+03C7, the Greek alphabet's twenty-second letter. The rows add the capital Χ, math styles such as 𝜒, the string χ², and the look-alikes X, × and ξ.

Chi is the Greek letter shaped like X

Capital chi, U+03A7, and the Latin X, U+0058, look the same and are two characters. Latin took the shape from Greek alphabets that wrote ks with chi. In standard Greek, chi is a kh sound that Latin letters write as ch, and the letter for ks is xi, ξ.

χ, x and × are three characters

Small chi is U+03C7, the Latin x is U+0078 and the multiplication sign × is U+00D7. Statistics writes χ² with the first.

As a Greek numeral chi is 600, written χʹ.
Plain LaTeX has \chi for the small letter and no macro for the capital.

Questions and answers

How do I type the chi symbol?

Chi has no Alt code, so copying is the short way. In HTML χ is the small letter and Χ the capital, χ and Χ as numbers. In LaTeX \chi prints χ in math mode.

Which Greek letter looks like X?

Chi. Its capital, Χ, is drawn like the Latin X. The Greek letter for the sound of x, ks, is a different one: xi, Ξ.

What does chi stand for?

Statistics writes chi-squared, χ², for a distribution and the tests that use it. Small χ also stands for the Euler characteristic of a surface, for electric or magnetic susceptibility, and in phonetic writing for a voiceless uvular fricative.

How do you say chi?

English says ky, with the vowel of my, and khee is also heard. Modern Greek writes the name χι.

How this list was compiled: Names, and the code points they belong to, are from UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt), printed in sentence case; its decomposition field is what says a math alphabet character is a plain letter in a font, or that an accented letter is a letter plus its marks. Aliases, notes and cross-references are from NamesList.txt of the same version (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt), the version a character was added in is from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt), and the years are from https://www.unicode.org/history/publicationdates.html. Alt codes are from the code page 437 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/PC/CP437.TXT). HTML entity names are from https://html.spec.whatwg.org/entities.json, the shortest standard name first. LaTeX macros are listed only when LaTeX's own fontdef.dtx (https://github.com/latex3/latex2e/tree/develop/base) declares them, matched to a code point through unicode-math-table.tex (https://github.com/latex3/unicode-math). A cell is empty where no such method exists. What chi is for, as https://en.wikipedia.org/wiki/Chi_(letter) records it: the twenty-second letter, its sound in ancient and in modern Greek, the two ways it is written in Latin letters, the numeral value 600, the two English ways of saying the name and its older Greek spelling, the local Greek alphabets that wrote ks with chi and the Latin X that came of it, the Cyrillic letter, chi-squared in statistics, the Euler characteristic, susceptibility and the phonetic use, the chi rho, and the characters it is not to be confused with. Xi as the letter for ks, and chi as the letter that gave the Latin X its form: https://en.wikipedia.org/wiki/Xi_(letter). The chi rho as the first two letters of a Greek word: https://en.wikipedia.org/wiki/Chi_Rho. A chi-squared test: https://en.wikipedia.org/wiki/Pearson's_chi-squared_test. The numeral table: https://en.wikipedia.org/wiki/Greek_numerals. The modern Greek name of the letter, the numeral stroke, and Coptic as a descendant of the Greek alphabet: https://en.wikipedia.org/wiki/Greek_alphabet. Listed: the two letters, the ten math alphabet forms, the raised and the lowered chi, the Cyrillic and Coptic letters, the chi rho, the Latin small chi, four characters it is mistaken for, and this site's own strings of two characters, each written the way a source writes it. Left out: the other Greek letters (xi appears once, as a look-alike), the Latin capital chi of version 8.0 and two more Latin chis of version 7.0, which a device with no font for them draws as empty boxes, the syllables of other scripts that only share the name, and the Coptic khi ro sign.
