History & usage: The RING EQUAL TO symbol, written as U+2257, is a math operator used in formulas and in user interfaces. It combines the idea of equality with a circular ring to show a special relation. In history, similar symbols appeared in mathematical texts to show a rounded or nuanced equality. In modern usage, it appears in textbooks and software to represent a relation that is equal in a ring or circular context, or to mark a specific equivalence. The symbol helps distinguish standard equality from a related concept in algebra or set theory. When used in code or formulas, it serves as a clear visual cue for a defined relation. It is commonly seen alongside other operators in equations and interfaces that require a compact symbol. Users may see it in math editors, calculators, and technical documents. The symbol is part of the common set of math symbols and supports clear communication without extra words. Understanding its role helps readers recognize the intended meaning in equations and UI elements.

Copy and input: the quickest method is to copy the character here. You can also insert it by its codepoint U+2257 in many development tools or editors. Some operating systems provide a character viewer or input palette that lets you search by name or code and insert the glyph into documents.

Display and fallback: if you see an empty box (tofu) or a placeholder rectangle, the active font might not include this codepoint. Switching to a font with broader Unicode coverage or using a fallback font usually fixes the issue. On the web, ensure the page’s font stack includes a general‑purpose fallback.
