#### Right angle conversion

In geometry and trigonometry, a right angle is an angle that bisects the angle formed by two halves of a straight line. More precisely, if a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

#### Grads conversion

The grad is a unit of plane angle that is equivalent to 1⁄400 of a circle. It is also known as gon or grade (not to be confused with gradient or radian unit). One grad equals 9⁄10 of a degree or π⁄200 of a radian.
