Degrees to Radians Formula How to Convert Degrees to Radians ?
As we know, Pi radians = 180° so we can write π rad = 180° and
1° = 180°/ π; 0.01745329252 and 1° = 0.01745329252; we can also write;
Radians = Degrees × π / 180°
Degrees & Radians Conversion Definition and Examples
Degree : A degree is a measurement of angle equal to 1/360th of a wheel/ circle. And, digit 360 has 24 divisors, creating it a relatively simple number to work with.
Radians : A radian is a measure of angle equal to the beginning to the end of an arc divided by the radius of the ring/ arc. π rad = 180°.
Here are few examples showing Degrees and Radians conversion using above formula:
Example – 1. Convert 30 degrees to radians?
using our formula Radians = Degrees × π / 180°
Radians = Degrees × π / 180° = 30 × π / 180° = 0.52359
Example – 2. Convert 180 degrees to radians?
using our formula Radians = Degrees × π / 180°
Radians = Degrees × π / 180° = 180 × π / 180° = 3.141592
