What Is the Angle Converter?
The **Angle Converter** is a free browser-based calculator that translates angle values and rotation metrics between Degrees (°), Radians (rad), Gradians (grad), Minutes ('), Seconds ("), Quadrants, Sextants, Octants, Signs, Revolutions (rev), NATO Mils, and Centrads.
Whether you're studying trigonometry and geometry, programming graphical vector shaders, adjusting navigation coordinates, calibrating telescope scopes, or detailing construction layouts, this converter generates instant conversions side-by-side.
Everything runs client-side in your local browser sandbox thread. Your data stays 100% on your device, ensuring maximum confidentiality and complete offline functionality.

Frequently Asked Questions
A radian is the standard unit of angular measure used in many areas of mathematics. It is defined as the angle subtended at the center of a circle by an arc that is equal in length to the radius. One full rotation ($360^\circ$) is exactly equal to $2\pi\text{ radians}$ (approximately 6.28318 rad).
A gradian (also known as gon or grade) is a unit of angular measurement equal to 1/400 of a full circle. A right angle is exactly equal to 100 gradians. Gradians are widely used in surveying and civil engineering in certain European countries.
