The formula behind Milradian is pretty damn simple, once you figure it out, you're golden.
Here's the formula S=R(Theta)
(Theta) is an angle, described in radians
A circle(360 degrees) is 2(Pi) radians, 90 degrees is (Pi)/2, 180 degrees is (Pi).
2X(Pi) (2X 3.14159...) comes out to approximately 6.283
so, on a circle with a radius of one foot, the circumference is 6.283 feet.
Now, we plug this into S=R(Theta)
A Milradian means quite literally a thousandth of a radian, so where we would plug in 2(Pi) for the S of a full circle,
you plug in (.001) for your Theta value
in case I haven't mentioned it, R is the radius of the circle.
so now our equation looks like this:
S=(distance in centimeters)X(Theta)
So, if you're ranging a target at 100 meters, you plug in 10,000
and if the Target is one milradian, plug in .001
result- (10,000 cm) x(.001 milradian)=(Your S value)= 10 cm.
And thats how it works. 200 meters, 20 cm, 300 meters, 30 cm, and so on.
Milradians are easy as hell when you use metric. if you're one of those heathens that still uses the english system, I guess you could use MOA, but the Engrish system is stupid when you want fast and easy notes. </div></div>
WOW!
Congrats...that's some serious math bullshit there.
Serves absolutely no purpose other than to confuse....but I guess it worked.
And although I speak perfect Engrish and use Mil based scopes...I have no clue how to use the metric system effectively. Good thing since Mils have nothing to do with the metric system.
A mil is 1/1000 of something...anything.
1 mile at a 1000 miles
1 yard at a 1000 yards
1 inch at a 1000 inches
Take 1 yard at 1000yds.....thats 36".
Moving the decimal place over you can see how that becomes 3.6" at 100yds.
3.6" equals 3.43 MOA....since MOA is an angular adjustment. 1 mil equals 3.43 MOA at <span style="text-decoration: underline">any</span> range.
Hard to understand? Here's a visual...
A mil is the center of a dot to the center of another dot....at <span style="text-decoration: underline">any</span> range! You spot your miss 1 mil low dial up 1 mil regardless of distance.
The "rough moa value" shown is just rounding the MOA value to 3.5 because our turrets that subtend in MOA are often in 1/4 MOA increments....you can dial dial 3.25 or 3.5 but not 3.43. </div></div>
Dude, it would have been a lot easier on a blackboard because of those damn greek letters these mathematicians love using, but either way, if you're into serious shooting, or adjusting fire, or anything that has to do with messing things up in the most awesome manner possible, Trigonometry rocks.
Hell, we learned this formula the first week, then last month we spent doing the math for polar fire missions. this week, we're working on the math behind wind drift and bullet drop. It should be called "Math for Badasses" in the course catalog.
