Mathematical Script Capital K Symbol
𝒦 is the Mathematical Script Capital K character (U+1D4A6) used for stylized math notation.
U+1D4A6
𝒦 (U+1D4A6) is a stylized “K” from the Mathematical Script block. It’s mainly used when you want a calligraphic/script look in math or typography. Below you’ll find practical ways to copy, identify, and use it.
Mathematical Script Capital K Symbol Meaning
𝒦 is the Unicode character “MATHEMATICAL SCRIPT CAPITAL K” (U+1D4A6). Like other mathematical script letters, it typically represents a variable, symbol, or labeled quantity in contexts such as equations, technical writing, or document styling where a script/calligraphic form is preferred. Because it is a specific typographic form, its exact meaning depends on the author’s notation rather than a universal symbolic meaning. In practice, you’ll mostly use it as a visual variant of a capital K rather than as a standalone icon.
Common uses
- •Labeling variables in equations with a script/calligraphic style
- •Typographic emphasis in math notes, textbooks, or presentations
- •Designing posters or slides that require a calligraphic K for consistency
- •Creating custom notation systems in educational or technical documents
- •Rendering a stylistic “K” in math-themed logos or branding elements
