Convert Degree to Radians Calculator

Converting degrees to radians is a common task in mathematics, physics, and engineering. Our easy-to-use degree to radians calculator simplifies this process, allowing you to quickly and accurately convert between these two angular measurements.

What are Degrees and Radians?

Before we dive into the conversion process, let’s understand what degrees and radians are:

Degrees: A unit of angular measurement where a full circle is divided into 360 equal parts.
Radians: A unit of angular measurement defined by the ratio of the arc length to the radius of a circle.

The Conversion Formula

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

radians = degrees * (π / 180)

Where π (pi) is approximately equal to 3.14159.

Examples of Degree to Radian Conversion

Here are some common angle conversions for reference:

Degrees	Radians
0°	0
30°	π/6

Frequently Asked Questions

Why is π radians equal to 180 degrees?

This relationship comes from the definition of a radian. Since the circumference of a circle is 2πr (where r is the radius), and a full circle is 360°, we can set up the equation: 2π radians = 360°. Simplifying this gives us π radians = 180°.

How do I convert radians back to degrees?

To convert radians to degrees, use this formula: degrees = radians \* (180 / π)

Are there any angles where degrees and radians are the same?

The only angle where the degree and radian measures are equal is 0°, which is also 0 radians.

How precise is the calculator's conversion?

Our calculator provides results accurate to several decimal places, which is sufficient for most practical applications.
