Arcminute to Turn Converter

Convert arcminutes to turns instantly. Free, bidirectional, and fully in-browser.

1 arcminute equals 4.62963e-5 turns — enter any arcminute value to convert it to turns instantly. This Arcminute to Turn converter is a client-side tool: it applies a single multiplication (turn = ′ × 4.62963e-5) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert turns back to arcminutes. A reference table lists common arcminute values already converted, and nothing you enter is sent to a server.

  The result updates as you type, and the swap button flips the conversion to turn → arcminute without reloading.
