How Many Gradians in a Full Circle?
Quick Answer
There are 400 gradians in a full circle.
360° = 400 gradians; 1 right angle = 100 grad
Understanding the Conversion
A full 360° rotation equals 400 gradians (also called gon or grad). The gradian was introduced during the French Revolution to decimalize angle measurement. A right angle is exactly 100 gradians, which makes surveying calculations simpler.
Formula
360° = 400 gradians; 1 right angle = 100 grad
Common Examples
| Description | Value |
|---|---|
| A right angle (90°) | 100 gradians |
| A straight angle (180°) | 200 gradians |
| Used in European surveying | 1 grad = 0.9 degrees |
