Copy and Paste Symbols: Math, Statistics, Physics, Chemistry

Copy math, statistics, physics, and chemistry symbols with Unicode, LaTeX, and HTML entity metadata.

At a glance

Computes: Unicode code point, LaTeX command, and HTML entity for each symbol you copy.
You supply: A search term or a category, or nothing at all if you browse.
Use when: You know the symbol you want and need to paste it somewhere exactly.
Not for: Finding out what an unfamiliar symbol means. Math and Science Symbols

How this keyboard is built

The keyboard is a finite set of high-use math and science symbols. Each key stores the glyph, Unicode code point string, LaTeX representation, HTML entity, category, and aliases. Search filters those fields locally.

Copying symbols that look alike but are not

Copying a symbol is only useful when it is the right code point. Several characters look identical in ordinary fonts but search, sort, normalize, and paste differently. Every key exposes its Unicode, LaTeX, and HTML representation so identity can be checked rather than inferred from appearance.

Infinity

The infinity sign is U+221E. Negative infinity is a minus sign followed by the same character, not a separate code point. The empty-set sign is a different mathematical object and should not be substituted merely because its outline is similar.

Degree sign

The degree sign is U+00B0. The masculine ordinal indicator is U+00BA and is a letter-like character, not a temperature or angle mark. Celsius and Fahrenheit compatibility characters also exist, although a degree sign followed by C or F is generally easier to typeset reliably.

Subscripts and superscripts

Subscript digits occupy the contiguous range U+2080 through U+2089. Superscript digits are split: one, two, and three remain in Latin-1, while zero and four through nine live in the U+2070 block. These fixed characters are useful in plain text; real typographic formatting is preferable when available because it scales with the surrounding type.

Greek letters

Greek mu and the micro sign can look identical, as can capital omega and the ohm compatibility sign. Use this keyboard for code-point identity. To learn a symbol's meaning, pronunciation, and field, use the math and science symbol lookup.
