O que é Angle Converter?
Angles are measured in degrees (°), radians (rad), or gradians (gon) depending on the field. Math and physics use radians. Navigation, surveying, and astronomy use degrees (often subdivided into arcminutes and arcseconds). Civil engineering in some countries uses gradians.
One full turn is 360° = 2π rad = 400 gon. This converter uses the radian as the base.
