# Gradians to Milliradians Conversion

Enter the angle in gradians below to get the value converted to milliradians.

**Results in Milliradians:**

^{g}= 15.707963 mrad

## How to Convert Gradians to Milliradians

To convert a gradian measurement to a milliradian measurement, multiply the angle by the conversion ratio. One gradian is equal to 15.707963 milliradians, so use this simple formula to convert:

The angle in milliradians is equal to the gradians multiplied by 15.707963.

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

^{g}= (5 × 15.707963) = 78.539816 mrad

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

## 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.

## Milliradians

A milliradian is equal to 1/1,000 of a radian. One degree is equal to 0.0573 milliradians and there are 6,283 milliradians in a full revolution/circle. The milliradian is also a commonly used unit in mathematics.

The milliradian is a multiple of the radian, which is the SI derived unit for angle. In the metric system, "milli" is the prefix for 10^{-3}. A milliradian is sometimes also referred to as a mil. Milliradians can be abbreviated as *mrad*; for example, 1 milliradian can be written as 1 mrad.
