What is a Radian?

A radian is the standard SI unit of angular measure, defined as the angle formed when the arc length equals the radius. One full rotation is 2π radians.

What is a Milliradian?

A milliradian (mrad) is 1/1000 of a radian. Often used in military and ballistics applications for calculating adjustments over long distances.

Conversion Formula

To convert Radian to Milliradian, use the formula:

Milliradian = Radian × (1.0000000000e+0 / 1.0000000000e-3)

This formula works by converting Radian into radians as the base unit, then converting that result into Milliradian. It ensures high-precision conversion.

Example: Convert 10 Radian to Milliradian:
10 × (1.000000e+0 ÷ 1.000000e-3) = 10000.00000 Milliradian
