Estimates Symbol
The ≙ symbol denotes “is estimated as” or “corresponds to an estimate” in mathematical and analytical contexts.
U+2259
≙ is the “estimates” symbol, Unicode U+2259. It’s commonly used to indicate a relationship based on estimation rather than exact equality. You can copy it directly or use its HTML, CSS, or JavaScript escapes.
Estimates Symbol Meaning
The symbol ≙ (Unicode U+2259, named “ESTIMATES”) is used to express an estimated equivalence: something is “approximately equal to” or “matches in an estimated sense.” In math writing, it can indicate that one quantity is being compared through an estimate rather than an exact identity. In technical notes, it may also show that two expressions correspond under an estimated model, approximation, or inferred relationship. Treat it as a “based on estimation” indicator—use it when you want to emphasize that the relationship is not strictly exact, while still asserting a meaningful correspondence.
Common uses
- •Writing approximate equivalences between quantities in math notes
- •Labeling estimated parameters or inferred relationships in reports
- •Indicating estimated match between two datasets or models
- •Using in technical documentation to contrast exact vs. estimated equality
- •Formatting equations or annotations in scientific and engineering text

FAQ
What does the ≙ symbol mean?
≙ is the “ESTIMATES” symbol. It’s used to indicate an estimated equivalence—an approximate correspondence rather than exact equality.
How do I type or paste ≙?
You can copy it directly from this page. Many systems also support typing it via Unicode input tools once you know the code point U+2259.
What are the Unicode and code escapes for ≙?
Unicode code point: U+2259. HTML entity: ≙. CSS escape: \\2259. JavaScript escape: \\u{2259}.
Is ≙ the same as ≈ (approximately equal to)?
They’re related, but ≙ is specifically the Unicode “ESTIMATES” relation. In writing, use it when you want to emphasize estimated equivalence/correspondence in an analytic or modeled sense.
