# Angle Converter: A Comprehensive Guide on Converting Angles

Angles are one of the fundamental concepts in geometry and trigonometry. They are present everywhere, from the angles between the hands of a clock to the angles between the sides of a triangle. Angles are measured in degrees, radians, and grads. Converting angles from one unit to another can be a daunting task, especially if you're not familiar with the process. In this article, we'll explore the concept of angle conversion, including why it's necessary and how to do it.

## Why do we need to convert angles?

There are different systems for measuring angles, and each system has its advantages and disadvantages. For example, degrees are widely used in everyday life, but radians are preferred in advanced mathematics and physics. Grads are rarely used, but they are still used in some engineering and surveying applications. Converting angles from one unit to another is necessary when working with angles in different systems. It's also helpful to have a good understanding of angle conversion if you need to work with angles in various contexts.

## The three angle systems: Degrees, Radians, and Grads

There are three main systems for measuring angles: degrees, radians, and grads. Degrees are the most commonly used system, and they're familiar to most people. A degree is defined as 1/360th of a complete revolution. Radians are used in advanced mathematics and physics. A radian is the measure of the central angle of a circle that intercepts an arc equal in length to the radius of the circle. Grads are used in some engineering and surveying applications. A grad is defined as 1/400th of a complete revolution.
