Approximately Symbol is a free, browser-based reference tool for anyone who needs to type, copy or understand the ≈ (approximately equal to) symbol.
The site collects every practical way to enter ≈ on any device: a one-click copy button, verified keyboard shortcuts for Windows and macOS, Alt codes, HTML entities, CSS and JavaScript escapes, and LaTeX commands such as \approx. Every code is listed in copy-ready form so developers and writers can paste it straight into their own work.
Beyond the symbol itself, the site explains what approximately equal actually means. A built-in tolerance checker compares two numbers under a tolerance you choose and shows whether they qualify as approximately equal, with the reasoning spelled out step by step. A companion table sets ≈ beside related relation symbols — =, ≠, ≃, ≅, ∼ and ≒ — and explains where each one is appropriate.
The whole site runs in the browser with no account, no upload and no tracking, and is written for US-English readers. Students, teachers, developers and technical writers use it as a quick lookup when a symbol has to be exactly right rather than almost right.
