Gradian: History, Measurement & Regions

In trigonometry, the gradian – also known as the gon (from Ancient Greek γωνία (gōnía) 'angle'), grad, or grade – is a unit of measurement of an angle, defined as one-hundredth of the right angle; in other words, 100 gradians is equal to 90 degrees. It is equivalent to ⁠1/400⁠ of a turn, ⁠9/10⁠ of a degree, or ⁠π/200⁠ of a radian. Measuring angles in…
