# 1.3. Converting Radians to Degrees

## Problem

When using the trigonometric functions of the `Math` class, all units are in radians; instead, you require a result in degrees.

## Solution

To convert a value in radians to degrees, multiply it by 180/π:

```using System;

{
double degrees = (180 / Math.PI) * radians;
return (degrees);
}```

## Discussion

All of the static trigonometric methods in the `Math` class use radians as their unit of measure for angles. It is very handy to have conversion routines to convert between radians and degrees, especially when displaying degrees to a user is more informative than displaying radians.

The equation for converting radians to degrees is shown here:

`degrees = (180 / Math.PI) * radians`

The static field `Math.PI` contains the constant π.
