How to Convert Gradians to Milliradians

To convert a measurement in gradians to a measurement in milliradians, multiply the angle by the following conversion ratio: 15.707963 milliradians/gradian.

Since one gradian is equal to 15.707963 milliradians, you can use this simple formula to convert:

milliradians = gradians × 15.707963

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

For example, here's how to convert 5 gradians to milliradians using the formula above.
milliradians = (5g × 15.707963) = 78.539816 mrad

How Many Milliradians Are in a Gradian?

There are 15.707963 milliradians in a gradian, which is why we use this value in the formula above.

1g = 15.707963 mrad

Gradians and milliradians 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.

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.

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.
