# Radians and the good news

The good news is you don’t have to remember

1 radian `=57.296^@`

Because it is so easy to work out what the degrees are.

So if:

`360^@=100%` of circle

`2pir=360^@`

`1r=x^@`

(Look at our section on percentages)

`(2pir)/r` | `=` | `360/x` |

`x` | `=` | `(360timesr)/(2pir)` |

`x` | `=` | `(360times cancelr)/(2pi cancelr)` |

`x` | `=` | `360/(2pi)` |

`x` | `=` | `57.296^@` |
