Most guys neglect the decimal points, and just live by 1MOA = 1"/100yrds, so at 200, 1MOA = 2", 1MOA at 300yrds = 3", 400yrds = 4MOA, etc etc. It makes life a lot simpler, and since not many of us actually shoot well enough to ever notice 0.047" discrepancy, this rule works.
Since your scope is a 1/8" per 100yrds adjustment, it's living by the 1MOA=1"/100yrds rule. Following that, at 100yrds, 1 click = 1/8" adjustment. At 50yrds, 1click = 1/16", at 200yrds, 1click = 1/4" (2/8"), at 300yrds, 1click = 3/8"... At 1,000yrds, 1click = 1 1/4" (10/8"). So the further out you're shooting, the less refinement in your adjustment you have, since you click the same angle, not the same displacement.

That's a typo in their ad copy. When you look at the scopes themselves, their "tech specs" online, or their owners manuals then you'll see that they are 1/8" per 100yrds, not 1/8 MOA.
Nikon Monarch 3 6-24x50mm
Their website (Tech Specs - Adjustment Graduation) says "1/8in". My Nikon's all say 1/4" or 1/8" on the turrets and in the owners manuals as well. The "ad copy" on the front page says "1/8 MOA", but if you zoom in on the picture of the scope turret RIGHT BESIDE THAT HEADLINE you'll see that the turret itself says "1 click = 1/8"/100yrds". Nikons are 1/8" per 100yrds or 1/4" per 100yrds, not MOA.
