Degrees to gradians – convert deg to grad
Convert degrees to gradians (deg to grad) for surveying, navigation and some legacy calculators that still use the grad scale. This page opens the main angle converter with deg → grad pre-selected.
Open the interactive deg → grad converter:
Use main converter (deg → grad) or switch to grad → degYou can also switch to radians or full turns on the homepage if you prefer those angle units.
Quick reference: degrees to gradians
360° equals 400 grad, so:
grad = degrees × 400 / 360 = degrees × 10 / 9
| Degrees (°) | Gradians (grad) |
|---|---|
| 45° | 50 grad |
| 90° | 100 grad |
| 180° | 200 grad |
| 270° | 300 grad |
| 360° | 400 grad |
Why convert degrees to gradians?
Gradians show up when you:
- Work with surveying or mapping tools that use the 0–400 grad scale.
- Use calculators that support DEG/RAD/GRAD modes.
- Prefer quarter-turns to be a clean 100 grad instead of 90°.
- Translate older technical documents that reference gradians.

All angle conversions go through radians internally, so degrees, gradians and turns stay perfectly in sync.
