Input the degrees of an angle to convert to radians of that angle.

## Introduction to degree and radian

Degrees and radians are units of angle. A brief introduction to degree and radian measure is as follow:

Degrees:
• A degree is an angle measurement equal to 1/360 of a circle, Number 360 has 24 divisors.
• A degree is the accepted SI unit of an angle for use with the metric system.
• A degree can be abbreviated as ‘deg’. For example 1 degree can be written as 1 deg.
• Protractors are mostly used in measuring the angles in degrees. They are semi-circle or full circle devices with the degree marks allowing users to measure an angle in degrees.

• A radian is the angle from the start and end of the circle or an arc divided by the radius of the circle or arc.
• One radian is equal to 180/π , which is approximately 57.29578 deg. There are approximately 6.28318 radians in a circle.
• The radian is the SI derived unit for angle in the metric system.

• Pi radians are equal to 180 degrees:
• one degree is equal to 0.01745329252 radians:

## How to convert degrees to radians?

Here in this article you can understand how to convert degrees into radians in terms of pi,
To convert degrees to radians without a calculator, use this formula for degrees to radians conversion:
or

EXAMPLE:
With an angle of 63 degrees, the radians of that angle would be:
calculated this gives an angle of 1.099 radians.
Alternate method,
To convert a degree into a radian, multiply the angle value by the decimal value for the ratio:
The value in radians is equal to degrees multiplied by 0.017453.
For example, here is how to convert 9 degrees to radians using the above formula,

Example
Convert an angle of 22° to radians:
