Java .toRadians()

The Math.toRadians() method returns the measurement of an angle in degrees to an equivalent angle in radians.

Syntax

Math.toRadians(deg)

• The deg argument is a double value.
• The conversion from degrees to radians is generally inexact.

Example

The following example uses Math.toRadians() to convert 180 degrees and 45 degrees to radians:

public class Main {
  public static void main(String[] args) {
    double deg1 = 180.0;
    double deg2= 45.0;
    System.out.println(Math.toRadians(deg1));
    System.out.println(Math.toRadians(deg2));
  }
}
