Gradian to Radian Converter
Convert gradians to radians instantly. Free, bidirectional, and fully in-browser.
1 gradian equals 0.01570796327 radians — enter any gradian value to convert it to radians instantly. This Gradian to Radian converter is a client-side tool: it applies a single multiplication (rad = grad × 0.01570796327) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert radians back to gradians. A reference table lists common gradian values already converted, and nothing you enter is sent to a server.
How to use Gradian to Radian Converter
- 1
Open Gradian to Radian Converter on AltFTool — it loads instantly in your browser.
- 2
Type the value you want to convert into the Gradian field.
- 3
Read the equivalent in radians in the result field, and copy it if needed.
- 4
Use the decimal-places slider for more or less precision, or press swap to convert radians to gradians.
Why use Gradian to Radian Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to radian → gradian without reloading.
Exact Angle math
The conversion uses the precise factor (rad = grad × 0.01570796327), 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 radians for a spec, listing, or report.
- Checking gradian↔radian figures while comparing products, datasets, or documentation.
- Learning the gradian-to-radian relationship from the worked formula and the common-value table.
Frequently asked questions
How many radians are in a gradian?
One gradian is 0.01570796327 radians. Multiply the gradian value by 0.01570796327 to convert. For example, 10 grad = 0.1570796327 rad.
What is the formula to convert gradians to radians?
rad = grad × 0.01570796327. This tool applies it automatically and shows a worked example: 10 grad = 0.1570796327 rad.
Can it convert radians back to gradians?
Yes. Press the swap button, or type into the radian field, and the tool converts radians to gradians using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard angle and rotation definition (rad = grad × 0.01570796327), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
