## Example Conversion

Let's take a look at an example. The step-by-step process to convert 2 quadrants to radians is:

2. Substitute the required value. In this case we substitute 2 for quadrant so the formula becomes: rad = 2 × 1.5707963268
3. Calculate the result using the provided values. In our example the result is: 2 × 1.5707963268 = 3.1415926536 rad

## Conversion Unit Definitions

A quadrant is an angular measure that is equal to one quarter of a circle or 90 degrees. The term "quadrant" comes from the Latin word "quadrans" which means "a quarter."
To better understand this definition, it's important to note that a circle is divided into 360 degrees. Each quadrant is a portion of the circle that spans 90 degrees or one quarter of the circle. When measuring angles using quadrants, angles are usually denoted using the quadrant symbol (Q), which is placed after the numerical value of the angle. For example, an angle of 2 quadrants would be written as 2Q or 180°.
The quadrant is not as commonly used as other angular measures such as degrees, radians, or mils, but it is still used in some fields such as astronomy, where it is used to measure celestial coordinates. In addition, the term "quadrant" is also used to refer to a device used in navigation and astronomy to measure the altitude of celestial objects.

A radian is a unit of angular measure that is used to quantify the size of an angle, particularly in trigonometry and calculus. One radian is defined as the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle.
To better understand this definition, it's important to note that a circle has a circumference of 2π times the radius, where π is the mathematical constant pi (approximately 3.14159). Therefore, an angle of one radian is subtended by an arc that is equal in length to the radius of the circle, which is one unit in length.
When measuring angles using radians, angles are usually denoted using the radian symbol (rad), which is often omitted for simplicity. For example, an angle of 2 radians would be written as 2 rad.
