HTML Entity for Almost Equal To (≈)
What You'll Learn
How to display the Almost equal to symbol (≈) in HTML using numeric references, the named entity ≈, or a CSS escape. Unicode’s official name is Almost equal to (U+2248). In HTML’s entity list the same code point is exposed as ≈ (“asymptotically equal”)—a historical label that still maps to ≈; always match the symbol to your textbook or style guide.
The character lives in the Mathematical Operators block (U+2200–U+22FF). You may write ≈, ≈, ≈, or \2248 in CSS content. Do not confuse it with Approximately equal or equal to (≊, U+224A) or the combining mark Almost equal to above (U+034C).

This example shows the Almost equal to symbol (≈) using hexadecimal code, decimal HTML code, the named entity ≈, and a CSS content escape on a pseudo-element:
<!DOCTYPE html>
<html>
<head>
<style>
#point:after{
content: "\2248";
}
</style>
</head>

<p>Almost Equal To using Hexa Decimal: ≈</p>
<p>Almost Equal To using HTML Code: ≈</p>
<p>Almost Equal To using HTML Entity: ≈</p>

≈ expands to the same ≈ as ≈.🧠 How It Works
Hexadecimal Code
≈ references Unicode 2248 in hexadecimal. The x prefix marks a hex numeric character reference.
Decimal HTML Code
≈ is the decimal code point 8776 for the same character—often used when authors think in decimal Unicode values.
Named Entity
≈ is the HTML named entity for U+2248 (“asymptotically equal” in entity lists). It keeps hand-written formulas readable.
CSS Entity (Escape)
\2248 is the CSS escape (four hex digits) used in content on ::before / ::after to emit ≈ without placing the raw character in HTML.
Same visual result
All methods render ≈. Unicode is U+2248 (Mathematical Operators, U+2200–U+22FF). Official Unicode name: Almost equal to. HTML also exposes it as ≈.
Use Cases
The Almost equal to symbol (≈, U+2248) fits these kinds of content:
Approximate measurements, tolerances, and order-of-magnitude comparisons.
Intro algebra and calculus where ≈ means “approximately equal to.”
Rounding summaries and asymptotic statements in plain HTML text.
Readable ≈ in hand-authored markup for formulas in prose.
Contrasting ≈ with ≊ (U+224A), ≌ (U+224C), and ≅ (U+2245).
Fallback HTML when LaTeX or MathML is not available for a single relation sign.

💡 Best Practices
Do
- Use UTF-8; prefer
≈in hand-authored HTML when readability matters - Define notation once (tooltip, glossary, or prose) so readers know how you use ≈ versus ≊ or ≌
- Pair with math fonts (STIX Two Math, Latin Modern Math, etc.) for consistent operator spacing
- Use numeric references in generated markup or XML-first pipelines if needed
- Use
\2248only in CSScontent, not inside HTML text nodes
Don’t
- Assume ≈ always means the same as ≊ or ≅ without checking your field’s convention
- Use ≈ alone as the only explanation of a subtle approximation for a general audience
- Mix hex, decimal, and named forms at random in one template without a style guide
- Paste CSS escapes into HTML markup (they belong in stylesheets)
- Confuse the HTML entity label “asymptotically equal” with every informal reading of ≈ in prose

❓ Frequently Asked Questions
≈ (hex), ≈ (decimal), ≈ (named), or \2248 in CSS content. All produce ≈.U+2248 (hex 2248, decimal 8776). Unicode’s official name is Almost equal to; it sits in the Mathematical Operators block (U+2200–U+22FF). HTML lists ≈ (“asymptotically equal”) for the same character.≈, ≈, or ≈. The CSS escape \2248 belongs in stylesheets, usually in the content property of ::before or ::after. Same glyph, different layers.≈ refers to U+2248 in HTML (“asymptotically equal” in entity documentation).Explore More HTML Entities!
