Just thought I would add for clarification that milliradians are not really metric. A radian is the the length of the radius of a circle applied to the circumference. Milli refers to one thousandth. So a milliradian is a one thousandth of a radian. Though not exact, it turns out that one mill at a thousand meters is close to one meter in width.
