Meaning and usage
A Unicode superscript form of 1.
For Superscript One (¹), use it in plain text for compact exponents or labels; use semantic math markup for complex expressions.
Pronunciation: superscript one
Formula examples
x¹How to type Superscript One
- Windows
- Open Character Map and search by name or Unicode U+00B9.
- macOS
- Open Character Viewer with Control–Command–Space and search by the symbol name.
- Microsoft Word
- In an equation, type ^{1} and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste ¹, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ¹, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ¹ or use Insert → Special characters. For structured math, use the equation editor and verify ^{1}.
- Excel
- Paste ¹ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Unicode superscript or subscript glyphs such as ¹ are plain text; use structured LaTeX or MathML scripts when nesting, accessibility, or reliable layout matters.
- For plain text, copy ¹ as U+00B9; for structured equations, use ^{1} in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Superscript One.
When to use ¹
- Use ¹ in plain text when a Unicode character is appropriate and the destination preserves U+00B9.
- Use ^{1} in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Superscript One is used in super sub with a field-specific convention.
Look-alikes and related characters
- ² — Superscript Two
- ₁ — Subscript One
- ⁰ — Superscript Zero
