## How to Convert Gradians to Revolutions

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

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

revolutions = gradians ÷ 400

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

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

^{g}÷ 400) = 1.25 r

Gradians and revolutions 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 Revolution?

A revolution, or turn, is equal to 1 rotation around a circle, or 360°. Revolutions are commonly used to measure the speed of rotation, for example when measuring the revolutions per minute (RPM) of a vehicle's engine.

A revolution is sometimes also referred to as a turn, cycle, or complete rotation. Revolutions can be abbreviated as *r*, and are also sometimes abbreviated as *rev* or *cyc*. For example, 1 revolution can be written as 1 r, 1 rev, or 1 cyc.
