1 tenth of an inch.....

1 moa at 300 is about 3 inches. I think 8 clicks will give you about 1 moa. 1 moa at 100 is 1 inch,1 moa at 200 is about 2 inches and so on. It is not exactly so, but it is close.
Do a search for JBM Ballistics and input your information. It is free and has a moa column and an inch column. Also wind and Mills if you want to compare moa to mills. It is pretty close most of the time.

Are you wanting to go up 3 inches or 3 minutes of angle?

At 300yrds, 1 click in your scope is not 0.1".
And as has been mentioned, if you want 3.1MOA instead of 3.1", then the distinction matters. If you need to dial 3.1", then click 8 clicks. If you need to dial 3.1MOA, you'll need 25clicks.
So...
Your Nikon Monarch 3 does NOT adjust 1/8MOA per click, it's 1/8" at 100yrds per click. Very slight difference, but a difference nonetheless.
1MOA = 1.0471955" at 100yrds, so most guys neglect that 0.0471955 part and say that 1MOA = 1" per 100.
Now, the difference is this:
If you have a scope that adjusts 1/8MOA per click, instead of 1/8" at 100yrds,then you'll have a bit of a difference. Nothing that would cause a miss, but a difference.
1MOA at 300yrds = 3.14", not 3". Does anybody really care if they are 0.14" off at 300yrds? Not usually, since none of us actually shoot that well.
Now HOW DO YOU ADJUST YOUR SCOPE:
8 clicks in that scope will give you 3" at 300yrds. There is no way for you to dial 3.1". 9 clicks in that scope will give you 3.375" of adjustment. At click subtension of 1/8" at 100yrds would be equivalent to 3/8" at 300, so the minimal adjustment you can make at 300 is .375".
Now, if you need 3.1MOA, not 3.1" - 3.1MOA is 9.3" at 300yrds (3.14" = 1MOA at 300yrds), and since each of your clicks is 3/8" at 300yrds, you'd have to click up 25 clicks (24.8clicks, to be exact).
EDIT - made correction for 3.1MOA = 9.3" = ~25clicks

8 clicks will get about 3 inches at 300 yards.

Your ballistic program sounds like it said 3.1 MOA. Three full MOA and one tenth of MOA
It may not know how many clicks it takes for you to get one MOA,
Look at it this way, if it said 3.5 MOA you would dial 3 MOA and four clicks since four clicks would be half a MOA in your scope

If your scope is 1/8 MOA clicks
1 click = .125 moa
2 click = .250 moa
3 click = .375 moa
4 click = .500 moa
5 click = .625 moa
6 click = .750 moa
and so on
1 click = .125 moa
2 click = .250 moa
3 click = .375 moa
4 click = .500 moa
5 click = .625 moa
6 click = .750 moa
and so on

His scope is NOT a 1/8MOA scope. It's a 1/8" at 100yrd scope. Nikon Monarch 3.

3.1 MOA to me is 3.. 3.15 MOA is 3 plus one click for 3.25..
You have 1/8 MOA so your round ups or downs will be closer..As for me,I can't shoot the difference for .15

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.

Yep I do and I also know it is dead along with IPHY. Mil is where it is at. I would put a smiley face but I am not kidding.
To the OP.... I also know you should set up your ballistic program to match the system you are running. It should have a setting for MOA or IPHY and your 1/8 clicks then you wont have these issues as it will tell you the clicks to crank.
