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.

The angle converter handles degrees, radians, gradians and turns so you can move between any of the common angle units.

Quick reference: turns to gradians

One full turn equals 400 gradians. So: grad = turn × 400. Examples:

Turns Gradians (grad)
0.25 turn100 grad
