How to Type Chemical Formulas & Equations Online

Writing chemical equations (like the combustion of methane) or formulas (like Glucose) in standard word processors is notoriously frustrating. Between manual subscript formatting and hunting for reaction arrows, a simple equation can take minutes.

The Challenge of Chemical Notation

Standard keyboards are designed for literature, not stoichiometry. Chemistry notation requires three specific formatting tools:

Step-by-Step Guide

Using our Chemistry Keyboard, you can type complete reactions in seconds:

Example: Photosynthesis Equation

6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂
  1. Type 6C on your keyboard.
  2. Click O.
  3. Click the subscript on our digital pad.
  4. Type + 6H... and so on.

Why Unicode Matters

Unlike Microsoft Word's subscript formatting, which is essentially a visual trick, our keyboard uses Unicode characters. This means when you copy "H₂O", the "₂" actually stays as a small "2" even when pasted into an email, a tweet, or a plain text editor.
