A degree(°) is a unit of measurement that is used to measure angles, and also longitude and latitude.
The radian(rad) is the SI derived unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics.
Formula to convert degrees to radians.
To convert degrees to rad we multiply by π out of 180° . We do this because of the fact that a full circle is 360 ° and which can also be written as also 2π radians. And we know that the value of pi here is 180°.
Theta(θ) is the angle in degrees.
Example:
Convert 60 ° to rad.
= 60 x (π ÷ 180)
= 1.0472 rads.
