Discover the ease of converting circle measurements into radians with Newtum's Circle to Radian Converter. A tool designed to pique your curiosity and simplify your calculations.

A circle is a two-dimensional shape consisting of all the points in a plane that are at a constant distance, known as the radius, from a fixed point, called the center. The distance around the circle, or the perimeter, is called the circumference. Circles are fundamental in geometry and appear in various natural and man-made forms.

A radian is a unit of angular measure used in mathematics and engineering. It is defined as the angle created by taking the radius of a circle and wrapping it along the circle's edge. One radian is the angle at which the arc length is equal to the radius. There are 2π radians in a full circle.

Degrees | Radians |
---|---|

30° | π/6 rad |

45° | π/4 rad |

60° | π/3 rad |

90° | π/2 rad |

120° | 2π/3 rad |

135° | 3π/4 rad |

150° | 5π/6 rad |

180° | π rad |

270° | 3π/2 rad |

360° | 2π rad |

**
Example 1:
**

Convert 90° to radians:

90° = π/2 rad

**
Example 2:
**

Convert 180° to radians:

180° = π rad

A brief history of the Circle to Radian Converter traces back to the study of geometry and trigonometry, where radians were created to provide a natural and proportional relationship between an angle and the length of its corresponding arc.
