because it seems that's the only thing rifle accuracy is specified as - LOL - at least that's all you ever seem to see and hear.
btw, i shot a .167 mRad group last week with my 7mag.
Correct me if I'm wrong here folks, but I thought MOA was set up for yards opposed to mil and meters. So....1 MOA at 100 yds is 1.05"...1 mil at 100 meters is 1 cm.
I use MOA because I'm use to yds.
Although the radian is a unit of measure, it is a dimensionless quantity. This can be seen from the definition given earlier: the angle subtended at the centre of a circle, measured in radians, is equal to the ratio of the length of the enclosed arc to the length of the circle's radius. Since the units of measurement cancel, this ratio is dimensionless.
if you are thinking in linear terms you are wrong... that is number one.
These are angles, so they work with anything when it comes to linear distances.
Minute of ANGLE... if you use the angle and ignore the linear distance things work much better. Same with milRADIANS which is also an angle.
Look at the definition, this explains it:

Look at this definition and see if you see a single linear distance in there: —One milliradian is an angle which subtends an arc whose length is 1/1000th of the distance from the vertex.
—In other words, one milliradian subtends an arc whose length is:
—
—1 yard at 1000 yards.
—1 meter at 1000 meters.
—1 mile at 1000 miles.
—1 league at 1000 leagues.
—1 fathom at 1000 fathoms.
—1 inch at 1000 inches.
—1 foot at 1000 feet.
—3.6 inches at 3600 inches (100 yards).
—1 centimeter at 100 meters
it works with anything... it is not constrained to ONE UNIT OF LINEAR DiSTANCE.
Stop using a linear measurement as a gauge with this stuff and life will be much better for you.

To do more exact math, here are some additional numbers:
360 degrees in one circle
21600 MOA in one circle
6400 Mils in one circle (Army)
6283 Mils in one circle (Marines)
