Gradian (gon)
The gradian divides a right angle into 100 parts and is used in some surveying and engineering tasks.
History: the gradian was introduced in France as a decimal angular measure where a right angle equals 100 gradians.
Quickly convert gradians to radians without lookup tables or manual math.
This page is focused on converting gradians to radians. Type a number into the first field and the result appears immediately in the second field.
Example: 1 gon = 0.0157079633 rad. Conversion formula: result = value × 0.015707963267949 / 1.
Use this converter for everyday calculations, study notes, engineering checks, and quick value verification without installing a separate app.

The radian is the main mathematical angle unit and expresses arc length divided by radius.
History: the radian is based on arc length divided by radius and became a natural angular unit in mathematics.
