Meaning and usage
A non-SI unit of length equal to 10⁻¹⁰ metre.
Prefer SI units where required, but angstrom remains common for atomic scales.
Pronunciation: angstrom
Formula examples
1\,\text{Å}=10^{-10}\,\text{m}How to type Angstrom
- Windows
- Open Character Map and search by name or Unicode U+00C5.
- macOS
- Open Character Viewer with Control–Command–Space and search by the symbol name.
- Microsoft Word
- In an equation, type \mathring{A} and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste Å, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste Å, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste Å or use Insert → Special characters. For structured math, use the equation editor and verify \mathring{A}.
- Excel
- Paste Å into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Keep Å attached to the correct quantity and follow the destination's unit, currency, spacing, and decimal conventions.
- For plain text, copy Å as U+00C5; for structured equations, use \mathring{A} in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Angstrom.
When to use Å
- Use Å in plain text when a Unicode character is appropriate and the destination preserves U+00C5.
- Use \mathring{A} in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Angstrom is used in physics, currency measurement with a field-specific convention.
Look-alikes and related characters
- ∆ — Laplacian Symbol
- ℏ — Reduced Planck Constant
- Ω — Ohm
