How to Convert Milliradians to Gradians

To convert a measurement in milliradians to a measurement in gradians, multiply the angle by the following conversion ratio: 0.063662 gradians/milliradian.

Since one milliradian is equal to 0.063662 gradians, you can use this simple formula to convert:

gradians = milliradians × 0.063662

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

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

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

What Is a Milliradian?

A milliradian is equal to 1/1,000 of a radian. One milliradian is equal to 0.0573 degrees 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 thousandths, or 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.

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.

300 grad270°
400 grad360°

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.

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.
