Math symbol typer

Type math and formulas the quick way and get the real symbols, ready to paste into any app. Free, no sign-up.

How to use it

Type in the box and the symbols appear as you go. When you are done, press Copy and paste the text wherever you need it.

  • <=, >=, !=, +- and ~= become ≤, ≥, ≠, ± and ≈.
  • ->, <-, => and <=> become →, ←, ⇒ and ⇔.
  • 4.7e-5 becomes 4.7×10⁻⁵, 3*4 becomes 3×4, and sqrt(2) becomes √2.
  • H2SO4, Fe3+ and SO42- become H₂SO₄, Fe³⁺ and SO₄²⁻ once you type the space after them.
  • 30deg, 5 m2 and 9.8 m/s2 become 30°, 5 m² and 9.8 m/s².
  • Type / and a name, such as /alpha, /integral or /arrow, then choose with the arrow keys and Enter. Or click any symbol under the box.

Why the symbols paste anywhere

Every symbol here is an ordinary Unicode character, not a picture or a formula, so it pastes as text into Google Docs, Word, an email, a chat or a form. The small digits in H₂SO₄ and 10⁻⁵ are characters of their own too, so they keep their place wherever the text goes.

Most fonts include them. If one shows up as an empty box, the font in that app is missing the character, and switching to a common font such as Arial or Times New Roman fixes it.

It leaves ordinary text alone

A score like 3-2, a range like 1-2 hours, a phone number, a grade like B+ or a name like PS5 keeps its characters. A hyphen between two numbers only becomes a minus sign when the line has an equals sign or another operator, and a formula is only formatted when nothing else could be meant. Ctrl+Z, or ⌘Z on a Mac, brings back what you typed.

Questions,
answered

Is this math symbol typer free?

Yes. It is free, with no account, and what you type stays in your browser.

How do I type a subscript, like the 2 in H₂O?

Type H2O and a space. Common formulas and ions get their subscripts and charges as soon as you finish them.

Will the symbols work in Google Docs or Word?

Yes. They are plain text characters, so they paste into Google Docs, Word, email and most other apps.
