## How to Convert Gradians to Circles

To convert a measurement in gradians to a measurement in circles, divide the angle by the following conversion ratio: 400 gradians/circle.

Since one circle is equal to 400 gradians, you can use this simple formula to convert:

circles = gradians ÷ 400

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

**For example,**here's how to convert 500 gradians to circles using the formula above.

^{g}÷ 400) = 1.25 cir

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

## What Is a Gradian?

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, or 1.570796 × 10^{-2} 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.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.

## What Is a Circle?

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.

A circle is more commonly used to describe a round, symmetrical shape with no corners or edges than it is to describe plane angle. The shape is described by its radius and circumference.
