Definition

What Is the Ring Equal To Entity?

Ring Equal To (≗) is the Mathematical Operators character at Unicode U+2257 (RING EQUAL TO). It is a relation symbol with a ring above an equals-like form — used in algebra and formal notation.

Remember

Character     ≗
Unicode       U+2257
Hex entity    &#x2257;
Decimal       &#8791;
Named entity  &cire;
CSS escape    \2257
Not the same  &eqcirc; (≖) · = · &compfn; (∘)

All of these produce the same glyph: ≗. Prefer &cire; when you want an explicit entity.

Reference

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Ring Equal To (≗)</title>
  <style>
    #point::after {
      content: "\2257";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x2257;</p>
  <p>Using HTML Code: &#8791;</p>
  <p>Using Named Entity: &cire;</p>
  <p id="point">Using CSS Entity: </p>
  <p><code>a &cire; b</code></p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+2257 → ≗ in HTML. The browser turns it into ≗.

2. Decimal: same code point as 8791 → ≗. Same result as hex.

3. Named: &cire; is the HTML5 name for this character.

4. CSS: use \2257 in content (not an HTML entity). #point::after appends that ≗ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with Ring Equal To.

Look-alikes

≗ ≠ ≖ ≠ =

&cire; is ring equal to. &eqcirc; is ring in equal to. = is plain equality — pick the relation you mean.

Not combining

Not a diacritic

This is a standalone math symbol. For a ring under a letter, use Ring Below (U+0325).

Fonts

Math glyph coverage

Specialized operators may be missing in some fonts. Test on your target devices or provide a fallback.

CSS vs HTML

Do not mix escapes

\2257 belongs in CSS. &cire; / ≗ / ≗ belong in HTML.

A11y

Add nearby words

Pair the glyph with letters (for example a &cire; b) or use aria-label when it stands alone.

Semicolon

End references

Always finish with ; — write &cire;, not &cire.

Ring Equal To (U+2257) and its entity forms (&cire;, ≗, ≗, CSS \\2257) are supported in all modern browsers. Glyph coverage depends on the font.
