Why this tool is useful
Use this converter when specifications, downloads or measurements are given in gradians, but your worksheet or destination requires radians. It avoids manual factor mistakes.

Gradians to Radians Converter
Convert gradians (gon) to radians (rad) with a transparent angle formula.
Ready. Your working data stays in this browser.
How it works
The browser converts gon to the shared angle base unit using scale 0.015708 and offset 0, then converts that base value to rad using scale 1 and offset 0.
Practical example
For example, entering 1 gon returns 0.01570796327 rad. Results include the formula and enough precision for a quick verification.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
