Radians to Gradians Converter
How to convert radians to gradians
gradians = radians × 63.6619772
To convert radians to gradians, multiply the number of radians by 63.6619772.
1 rad = 63.6619772 gon
Examples
- 1 rad × 63.6619772 = 63.6619772 gon
- Π radians, a half turn: 3.14159265 rad × 63.6619772 = 200 gon
Good to know
The gradian is the "GRAD" mode on scientific calculators. It is not the same as a degree, and it is unrelated to the percent grade of a slope.

Unit definitions
- Radian (rad)
- The radian is the SI unit of angle: the angle at the center of a circle subtended by an arc equal in length to the radius. A full turn is 2π radians, so one radian is 180/π degrees, about 57.2958°.
- Gradian (gon)
- A gradian, also called a gon or grad, is 1/400 of a full turn, exactly 0.9 degrees, so a right angle is 100 gradians. It is used in surveying, mainly in continental Europe.
