## How to Convert Circles to Gradians

To convert a circle measurement to a gradian measurement, multiply the angle by the conversion ratio. One circle is equal to 400 gradians, so use this simple formula to convert:

The angle in gradians is equal to the circles multiplied by 400.

**For example,**here's how to convert 5 circles to gradians using the formula above.

^{g}

Circles and gradians are both units used to measure angle. Keep reading to learn more about each unit of measure.

## Circles

A circle is the equivalent of 1 revolution around a circle, or 360°.

A circle is sometimes also referred to as a revolution. Circles can be abbreviated as *cir*, for example 1 circle can be written as 1 cir.

## Gradians

A gradian is equal to 1/400 of a revolution or circle, or 9/10°.
The grad, or gon, is more precisely defined as (π/200) radians.^{[1]}

This unit simplifies the measurements of right angles, as 90° is equal to 100 gradians.

Gradians | Degrees |
---|---|

0 grad | 0° |

100 grad | 90° |

200 grad | 180° |

300 grad | 270° |

400 grad | 360° |

A gradian is sometimes also referred to as a grad, gon, or grade. Gradians can be abbreviated as * ^{g}*, and are also sometimes abbreviated as

*gr*or

*grd*. For example, 1 gradian can be written as 1

^{g}, 1 gr, or 1 grd.
