Approximately Symbol

Approximately Symbol is a free, no-sign-up reference page for the ≈ sign, built for people who need the right character and the right code without guessing between symbols that look almost the same.

The page opens with a single copy button for ≈, so the character can go straight into a document, a message or a source file. Every common representation of the same character is listed underneath with its own copy control: Unicode U+2248, HTML ≈, hex ≈, LaTeX \approx, CSS \2248 and JavaScript \u2248. The character names and code points are checked against the Unicode Consortium charts, with the last verification date shown on the page.

A plain-English section explains what ≈ means. It is read as "approximately equal to", as in π ≈ 3.14, where the right-hand side is a rounded value rather than an exact replacement for π. The page lists the situations where the sign is the honest choice: a value has been rounded or estimated, a measurement carries a tolerance, or writing an exact equality would be misleading.

There is also a small tolerance calculator. You enter two numbers and the maximum difference your context allows, and the page reports whether the pair is approximately equal under that tolerance and by how much they differ. The tolerance is deliberately left to the visitor, because what counts as close enough depends on the situation.

For typing rather than copying, a verified input-method section covers the routes documented by their vendors: copying from the page on any device, the Alt+X Unicode conversion in Microsoft Word on Windows after typing 2248, and the macOS Character Viewer search for "almost equal". Each method links to its source.

The site also provides a keyboard guide page and a comparison of the related equality symbols, so a reader can tell ≈ apart from =, ≃, ≅ and the other relation signs that are easy to mix up. Everything is free and anonymous: no account, no email, no paywall.
