How it works

Science symbols to copy, starting with Atom symbol. Chemistry signs, Greek letters of physics, units and typed formulas such as H₂O follow, then lab emoji and biology emoji. Which signs count as science is this page's own pick.

Read the full guide

Physics symbols copy and paste

Every tile in Physics symbols and Greek letters is plain text, so it pastes into a document, a slide or a chat. The list under the tool says what each letter stands for: lambda for wavelength, nu for frequency, rho for density, tau for torque.

Small numbers in a formula

The 2 in H₂O is a character of its own, Subscript two, not a smaller font, so a formula copied here keeps its low numbers wherever it lands. Formulas, typed has 14 ready-made; the low digits for your own are in Chemistry signs for equations.

  • The pair of half arrows, Equilibrium arrows, is the sign for a reaction in equilibrium.
  • Math signs such as ∞ and √ are on math symbols; the whole alphabet is on Greek letters.

Questions and answers

Is there a chemistry emoji?

Two. CLDR, Unicode's list of search words, files chemistry under Alembic emoji and Test tube. Test tube is also one of the six it files under lab, with Lab coat, Petri dish, Microscope and the two magnifying glasses.

What are the biology symbols?

Unicode names no character for biology. The two signs biology borrows are Female sign and Male sign, which Carl Linnaeus used for flowers from 1751. CLDR files biology under one emoji, Petri dish, and biologist under Dna, Petri dish and the scientists.

Is there a physics emoji?

No emoji is filed under physics. CLDR files physicist under the three scientists and science under seven emoji, among them Telescope, Microscope and Satellite antenna. Atom symbol emoji and the rest of its row are this page's pick.

Is there a marine biology symbol?

Not in Unicode. CLDR files marine under two emoji, Jellyfish and Orca; Orca is from Emoji 17.0, newer than this page takes. Coral, a dolphin, a whale, an octopus and a tropical fish are this page's picks.

How this list was compiled: Built on 2026-10-03 from Unicode's own files, each read that day. Every character that is not an emoji was fetched by its name from UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt); its block is from Blocks.txt and the Unicode version that added it from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/Blocks.txt, https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt). Where a note quotes the names list, that is NamesList.txt 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt). The emoji, their names, code points and Emoji versions are from the Unicode emoji list, version 18.0 (https://www.unicode.org/Public/18.0.0/emoji/emoji-test.txt), and their search words from the CLDR English annotations (https://github.com/unicode-org/cldr/blob/main/common/annotations/en.xml and https://github.com/unicode-org/cldr/blob/main/common/annotationsDerived/en.xml): CLDR files lab under six emoji, chemistry under two, biology under one and physics under none; every other emoji here is this site's own pick. What a Greek letter stands for is from Wikipedia, Greek letters used in mathematics, science, and engineering (https://en.wikipedia.org/wiki/Greek_letters_used_in_mathematics,_science,_and_engineering); the equilibrium arrows and the delta for heat from Chemical equation (https://en.wikipedia.org/wiki/Chemical_equation); the ten chemical formulas from Glossary of chemical formulae (https://en.wikipedia.org/wiki/Glossary_of_chemical_formulae); the four physics formulas from Mass–energy equivalence, Newton's laws of motion, Ohm's law and Ideal gas law (https://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalence, https://en.wikipedia.org/wiki/Newton%27s_laws_of_motion, https://en.wikipedia.org/wiki/Ohm%27s_law, https://en.wikipedia.org/wiki/Ideal_gas_law); the use of the female and male signs in biology from Gender symbol (https://en.wikipedia.org/wiki/Gender_symbol). Wikipedia text is under CC BY-SA 4.0 and was read on 2026-10-03; only facts are taken, no wording. Unicode data is used under the Unicode terms of use (https://www.unicode.org/terms_of_use.html). Which signs and emoji count as science is this site's own choice. Each character was drawn with a computer's system fonts before it was kept. Math signs, the full Greek alphabet, hazard signs and space emoji have pages of their own and are not repeated here. Licence: own work
