# Excel DEGREES Function

**angle**- Angle in radians that you want to convert to degrees.

The DEGREES function takes an angle in radians and converts it to degrees. Radians measure angles using the radius of a circle, as illustrated in this image:

To convert degrees back to radians, you can use the RADIANS function.

### Converting degrees to radians manually

Because Pi = 180°, the general formula for degrees to radians is **degrees * PI()/180**. For example, to convert 45° to radians, the Excel formula would be 45*PI( )/180 which equals 0.7854 radians. More examples in the table below:

Formula | Degrees |
---|---|

=2*PI() | 360 |

=PI() | 180 |

=90*PI()/180 | 90 |

=45*PI()/180 | 45 |

=30*PI()/180 | 30 |

=20*PI()/180 | 20 |
