Gradians to Degrees Converter gon → °
1 gradian (gon) = 0.9 degrees (°). Type a value below — the conversion happens instantly, entirely on your device.
1 gon = 0.9 °
1 gradians = 0.9 degrees
1 × 0.9 = 0.9
1 gon equals 0.9 °, so multiplying by 0.9 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert gradians to degrees
degrees = gradians × 0.9 — multiply the gradian value by 0.9.
Example: 10 gon = 9 °.
To convert the other way: gradians = degrees ÷ 0.9 — or use the dedicated ° to gon converter .

About the units
What is a gradian?
Also called the gon or grad — 400 gradians make a full circle, so a right angle is exactly 100 gon. Used in surveying and some European engineering.
What is a degree?
The everyday angle unit — 360 degrees make a full circle, so a right angle is 90° and a straight line 180°. Divided into 60 arcminutes each of 60 arcseconds.
Frequently asked questions
How many degrees are in 1 gradian?
