Enter the angle in milliradians below to get the value converted to gradians.  To convert a milliradian measurement to a gradian measurement, multiply the angle by the conversion ratio. One milliradian is equal to 0.063662 gradians, so use this simple formula to convert:

The angle in gradians is equal to the milliradians multiplied by 0.063662.

For example, here's how to convert 5 milliradians to gradians using the formula above.
5 mrad = (5 × 0.063662) = 0.31831g

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.

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.

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

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 1g, 1 gr, or 1 grd.
