Strictly Equivalent To Symbol
≣ means “strictly equivalent to” in mathematical notation.
U+2263
The symbol ≣ is a math operator used to express a strict form of equivalence. It’s handy when you want to be precise about sameness, beyond a looser “equivalent” relation. You can copy it directly or use its Unicode/HTML forms in documents and code.
Strictly Equivalent To Symbol Meaning
The symbol ≣ (Unicode U+2263, “STRICTLY EQUIVALENT TO”) is used in mathematical contexts to denote that two expressions are strictly equivalent under the intended definition of equivalence. In typical usage, it signals a stronger or more specific kind of equivalence than a general “equivalent to” sign, depending on the surrounding system or textbook. You’ll most often see it in formal writing, proofs, and technical documents where the author wants readers to distinguish strict equivalence from other comparison relations. When using it, make sure the relation matches the notation conventions of your field or course materials.
Common uses
- •Writing formal math notes to indicate strict equivalence between expressions
- •Documenting proof steps where a stronger equivalence relation is required
- •Labeling properties in technical diagrams or worksheets for students
- •Formatting scientific/engineering documentation that uses strict equivalence notation
- •Using the symbol in markup or UI text to represent the intended relation
Examples
≣ Strictly equivalent to
- ≣A ≣ B means A and B are strictly equivalent.
- ≣From definition, f(x) ≣ g(x) for all x in the domain.
- ≣We show that (S, ~) ≣ (T, ≡) under the strict relation.
- ≣This transformation preserves strict equivalence: E1 ≣ E2.
- ≣In this context, x ≣ y indicates strict equivalence.

FAQ
What does ≣ mean?
≣ means “strictly equivalent to” and is commonly used as a math relation symbol.
How do I type or insert the symbol ≣?
Copy it directly (≣), or insert it by Unicode U+2263, HTML entity ≣, CSS escape \\2263, or JavaScript escape \\u{2263}.
Is ≣ the same as the normal equivalence symbol?
Not always. ≣ is specifically the “strictly equivalent to” sign; whether it differs from a general equivalence sign depends on the notation conventions used in your context.
Where is ≣ commonly used?
You’ll most often see ≣ in formal math writing, proofs, technical documents, and educational materials where strict equivalence notation is required.
