Re: Milrads and MOA?

I'm afraid that turns out not to be the case.
A minute of angle, by definition, is 1/60th of one degree.
Note the period after the sentence above.
That means that one minute of angle is an angle which subtends an arc whose length is 1.047 inches at a distance of one hundred yards.
The difference between the arc length and the chord length is 0.000004166666616672248 percent, so that's <span style="font-weight: bold"><span style="font-style: italic">not</span></span> why people refer, incorrectly, to an angle whose value is 1.00 inches at a distance of 100 yards as an MOA.
And there are people who define a "mil" as an angle of which there are 6200, 6400, and some other values in a circle, rather than the correct value for a milliradian.
Calling something which it isn't doesn't make it whatever you call it.
Both a minute of angle and a milliradian have one, and only one, correct angular value.
Another period, one will note.
