You can do the reverse unit conversion from degree to milliradian, or enter any two units below:

The SI prefix "milli" represents a factor of
10^{-3}, or in exponential notation, 1E-3.

So 1 milliradian = 10^{-3} radians.

The definition of a radian is as follows:

In mathematics and physics, the radian is a unit of angle measure. It is the SI derived unit of angle. It is defined as the angle subtended at the center of a circle by an arc of circumference equal in length to the radius of the circle. Angle measures in radians are often given without any explicit unit. When a unit is given, sometimes the abbreviation rad is used, sometimes the symbol c (for "circular").

A degree (or in full degree of arc), usually symbolized by the symbol °, is a measurement of plane angles, or of a location along a great circle of a sphere (such as the Earth or the celestial sphere), representing 1/360 of a full rotation.
