## How to Convert Revolutions to Gradians

To convert a revolution measurement to a gradian measurement, multiply the angle by the conversion ratio.

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

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

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

^{g}

### How Many Gradians are in a Revolution?

There are **400** gradians in a revolution, which is why we use this value in the formula above.

1 r = 400^{g}

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

## Revolutions

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.

## 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, 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 formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.
