Formula

turn × 400 = gon

Example: 1 turn = 400 gon

What is Turn?

The turn represents one complete rotation, equal to 360 degrees, 2 pi radians, or 400 gradians. It is the most intuitive angular unit in everyday language: a "half turn" is 180 degrees, and a "quarter turn" is 90 degrees. In sports, figure skating jumps are described in turns (a triple axel is 3.5 turns), and skateboard tricks use 360 for one full rotation. In engineering, rotational speed in RPM is based on the turn.

What is Gradian?

The gradian, also called the gon, was introduced during the French Revolution alongside the metric system. It divides a right angle into 100 gradians, making a full circle 400 gradians. This unit is primarily used in surveying, especially in France and Germany, where survey instruments may be graduated in gradians. The advantage is that a right angle is exactly 100, simplifying slope calculations. One gradian equals 0.9 degrees.
