Turn to Gradian Converter

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

1 turn equals 400 gradians — enter any turn value to convert it to gradians instantly. This Turn to Gradian converter is a client-side tool: it applies a single multiplication (grad = turn × 400) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert gradians back to turns. A reference table lists common turn values already converted, and nothing you enter is sent to a server.

Why use Turn to Gradian Converter

• Instant, both ways

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

• Exact Angle math

  The conversion uses the precise factor (grad = turn × 400), so the number matches a manual calculation to the decimal places you choose.

• Adjustable precision

  A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.

• Private and free

  Everything runs locally in your browser — no upload, no account, no limit on conversions.

Common use cases

• Converting a turn measurement to gradians for a spec, listing, or report.
