Geometrically, there are 6283.185... mils around a circle.
No - actually there are 6.282722513 ...(to infinity) radians because Pi is used as part of the calculation (circumference of a circle) and Pi is an irrational number (cannot be expressed as a ratio of two integers) and will go to as many places as you care to carry it.
The number of radians in a circle (6.283) is rounded UP to 6.283 from 6.2827.
"Milli" is commonly used in units of measurement to denote a factor of one thousandth.
So, a "milliradian" is 1/1000 of a radian meaning - you take the previously calculated 6.283 and multiply by 1,000 = 6283 to get the number of radians in a circle. 6283 is the correct number to use as it has been arrived at by rounding up from the 1/10,000 decimal place.
I'm surprised you didn't point all of this out just to add more confusion to the simple process of using a Mil marked scope...
However, all of this is just like saying you can't accurately calculate the circumference of a circle because Pi is part of the calculation (2 x Pi x R).
You can never get the real measurement because Pi goes to as many places as you'd care to carry it out - but, after 0.0001 do you really care, except in specialized scientific or manufacturing applications?
If it's accurate to 1/10,000 do you need more for practical usage for aiming a rifle?
