# How to Convert Degrees to Radians

## Converting Degrees to Radians – A Necessary Skill for Any Math Enthusiast

If you’re interested in math, or have taken any math course in school, you must have heard about the conversion of degrees to radians. It’s an essential mathematical skill, which is required to solve complex problems in various fields such as geometry, physics, and engineering. In this post, we’ll take a closer look at this conversion and why it’s essential to acquire this skill, along with some software reviews and tutorials to help you learn.

## Degrees vs. Radians – What’s the Difference?

To understand the conversion of degrees to radians, we must first understand what radians are.

Radians are a unit of measurement for angles, just like degrees. One radian is defined as the angle subtended by an arc of the circle that’s equal in length to the radius of the circle. That’s a mouthful, so let’s break it down.

Imagine a circle with a radius of 1 unit. Now, draw an arc from one end of the radius to the other end, such that the length of the arc is equal to the length of the radius. The angle enclosed between the two radii is one radian. The following image depicts this concept:

## Conversion

To convert degrees to radians, we use the following formula:

radians = (degrees * pi) / 180

Where pi is a mathematical constant, usually approximated to 3.14159.

For example, suppose we want to convert 90 degrees to radians. Using the above formula, we get:

radians = (90 * 3.14159) / 180

Therefore, 90 degrees is equal to 1.5708 radians.
