Turns to gradians – convert turns to grad
Convert turns to gradians (full rotations to grad) for surveying, navigation, CAD, maths and engineering. A complete circle is 1 turn, which equals 400 gradians.

Quick reference: turns to gradians
One full turn equals 400 gradians. So: grad = turn × 400. Examples:
| Turns | Gradians (grad) |
|---|---|
| 0.25 turn | 100 grad |
| 0.5 turn | 200 grad |
| 0.75 turn | 300 grad |
| 1 turn | 400 grad |
| 1.5 turns | 600 grad |
| 2 turns | 800 grad |
Why convert turns to gradians?
Turns to grad is useful when you:
- Convert between full rotations and grad-based angle systems.
- Work with surveying or levelling instruments calibrated in gradians.
- Translate graphics or animation rotations into engineering angles.
- Teach relationships between degrees, radians, gradians and turns.

Because a right angle is 100 grad, many surveying calculations become simple addition and subtraction in the gradian system.
