Gradian to Degree Converter

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

1 gradian equals 0.9 degrees — enter any gradian value to convert it to degrees instantly. This Gradian to Degree converter is a client-side tool: it applies a single multiplication (° = grad × 0.9) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert degrees back to gradians. A reference table lists common gradian values already converted, and nothing you enter is sent to a server.

Why use Gradian to Degree Converter

• Instant, both ways

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

• Exact Angle math

  The conversion uses the precise factor (° = grad × 0.9), 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 gradian measurement to degrees for a spec, listing, or report.
