Named Entity
≗ is the semantic named entity for U+2257—the easiest to read in source HTML for ring equality notation.
Hexadecimal Code
≗ uses the Unicode hexadecimal value 2257. The x prefix indicates hexadecimal format.
Decimal HTML Code
≗ uses the decimal Unicode value 8791 to display the same character.
CSS Entity
\2257 is used in CSS stylesheets in the content property of pseudo-elements like ::after.
Same visual result
All four methods produce ≗. Unicode U+2257 sits in the Mathematical Operators block. Previous: Ring Below (U+0325, combining mark).
Use Cases
The Ring Equal To symbol (≗) is commonly used in:
Represent ring equality in formulas and mathematical documentation.
Use in research papers and scientific documentation.
Include in proofs and formal logic documentation.
Display in algebraic expressions and algebra textbooks.
Use in set-theoretic notation and mathematical set operations.

💡 Best Practices
Do
- Prefer
≗for readable source markup - Distinguish ≗ from ≖ (ring in equal to) and = (equals sign)
- Add
aria-labelfor standalone symbols in UI - Test the glyph across browsers and math fonts
- Pair ≗ with plain text on first use (e.g. “ring equal to”)
Don’t
- Confuse ≗ with ≖ (ring in equal to) or ∘ (ring operator)
- Use CSS escape
\2257inside HTML text nodes - Use HTML entities in JS (use
\u2257instead) - Mix entity styles randomly in one file
- Assume all fonts render ≗ at the same size as text
