Equivalent To Symbol
≍ means “equivalent to” and is used to express that two expressions are essentially the same in a given context.
U+224D
The symbol ≍ is commonly read as “equivalent to.” It appears in math, logic, and technical writing when you want to indicate a form of equivalence between quantities or statements. Below are practical ways to copy and use it correctly.
Equivalent To Symbol Meaning
≍ is the Unicode symbol named “EQUIVALENT TO” (U+224D). Visually, it places two tilde-like strokes on each side, suggesting a relationship of equivalence rather than strict equality. In math and related writing, ≍ is often used to communicate that two expressions are equivalent in a specific sense—such as having the same behavior, matching under a particular approximation, or representing the same object up to an understood notion of equivalence. Because “equivalent” can vary by field, the exact interpretation depends on the surrounding definitions or conventions in the document.
Common uses
- •State that two expressions are equivalent under a defined equivalence relation in math notes
- •Write “equivalent to” in technical explanations where equality is too strict
- •Indicate asymptotic equivalence between functions in calculations and summaries
- •Present substitutions or transformations that preserve meaning or structure
- •Label relationships in diagrams, captions, and documentation for clarity
Examples
≍ Equivalent to Symbol
- ≍Let f(x) ≍ g(x) for large x.
- ≍The two forms are equivalent to each other: A ≍ B.
- ≍We write h(n) ≍ k(n) to compare growth rates.
- ≍Under the given definitions, statement S ≍ statement T.
- ≍After transformation, the result is equivalent to the original expression: ≍.

FAQ
What does the symbol ≍ mean?
≍ is read as “equivalent to” and is used to express that two expressions are equivalent in a particular sense defined by the context.
Is ≍ the same as = (equals)?
Not necessarily. While ≍ indicates equivalence, it does not always mean strict equality; the exact meaning depends on the conventions used around it.
How can I type ≍ on a computer?
You can copy/paste it directly. You can also use Unicode U+224D, or escapes like HTML entity ≍ and CSS/JS Unicode escapes such as \\224D or \\u{224D}.
Where is ≍ commonly used?
It’s most common in math, scientific writing, and technical documentation where authors need to indicate a form of equivalence rather than strict equality.
