degrees() and radians() are methods specified in math module in Python 3 and Python 2.
Often one is in need to handle mathematical computation of conversion of radians to degrees and vice-versa, especially in the field of geometry. Python offers inbuilt methods to handle this functionality. Both the functions are discussed in this article.

radians()

This function accepts the “degrees” as input and converts it into its radians equivalent.

Syntax : radians(deg) Parameters : deg : The degrees value that one needs to convert into radians Returns : This function returns the floating point radians equivalent of argument. Computational Equivalent : 1 Radians = 180/pi Degrees.

Code #1 : Demonstrating radians()

Python3

import math

print("180 / pi Degrees is equal to Radians : ", end ="")

print (math.radians(180 / math.pi))

print("180 Degrees is equal to Radians : ", end ="")

print (math.radians(180))

print("1 Degrees is equal to Radians : ", end ="")

print (math.radians(1))

Output:

180/pi Degrees is equal to Radians : 1.0
180 Degrees is equal to Radians : 3.141592653589793
1 Degrees is equal to Radians : 0.017453292519943295

degrees()

This function accepts the “radians” as input and converts it into its degrees equivalent.

Syntax : degrees(rad) Parameters : rad : The radians value that one needs to convert into degrees. Returns : This function returns the floating point degrees equivalent of argument. Computational Equivalent : 1 Degrees = pi/180 Radians.

Code #2 : Demonstrating degrees()

Python3

import math

print("pi / 180 Radians is equal to Degrees : ", end ="")

print (math.degrees(math.pi / 180))

print("180 Radians is equal to Degrees : ", end ="")

print (math.degrees(180))

print("1 Radians is equal to Degrees : ", end ="")

print (math.degrees(1))

Output:

pi/180 Radians is equal to Degrees : 1.0
180 Radians is equal to Degrees : 10313.240312354817
1 Radians is equal to Degrees : 57.29577951308232

Application : There are many possible applications of these functions in mathematical computations related to geometry and has a certain applications in astronomical computations as well.

The measurements of angles in mathematics are done using these two units of measurement called degree and radian. They are frequently used in math calculations involving angles and need conversion from one value to another. In python we can achieve these conversions using python functions.

degrees() Function

This function takes radian value as parameter and return the equivalent value in degrees. The return is a float value.

Example

Live Demo

import math
# Printing degree equivalent of radians.
print("1 Radians in Degrees : ",math.degrees(1))
print("20 Radians in Degrees : ",math.degrees(20))
print("180 Radians in Degrees : ",math.degrees(180))

Output

Running the above code gives us the following result −

1 Radians in Degrees : 57.29577951308232
20 Radians in Degrees : 1145.9155902616465
180 Radians in Degrees : 10313.240312354817

radians() Function

This function takes degree value as parameter and return the equivalent value in radians. The return is a float value.

Example

Live Demo

import math
# Printing radian equivalent of degrees.
print("1 degrees in radian : ",math.radians(1))
print("60 degrees in radian : ",math.radians(60))
print("180 degrees in radian : ",math.radians(180))

Output

Running the above code gives us the following result −

1 degrees in radian : 0.017453292519943295
60 degrees in radian : 1.0471975511965976
180 degrees in radian : 3.141592653589793

Degrees and Radians() using numpy

numpy package also has inbuilt functions which can directlyconver degrees to radian and vice versa. These functions are names deg2rad and rad2deg.

Example

Live Demo

import numpy as np
# Printing radian equivalent of degrees.
print("1 degrees to radian : ",np.deg2rad(1))
print("1 radian to degree : ",np.rad2deg(1))

Output

Running the above code gives us the following result^−

1 degrees to radian : 0.017453292519943295
1 radian to degree : 57.29577951308232
