Ok so your question doesn't really make sense. Here is a quick down and dirty MOA for dummy's explanation.

Moa is an angular form of measurement. For arguments sake this is 1"@100yds. This translates to 2" @200 3" @300 ...and so on. So 1 moa= 10" @ 1000yds. 2 moa= is also 10" at 500 yds. make sense?
When dialing drops ( or windage) on your turret you will usually find # 1-14 ( 15 moa per rotation)and three hash marks after each whole number. These will be .25, .5, and .75 moa respectively. Keep in mind what 1 moa is at each distance. Ie at 200 yds the .5 moa will move your reticle 1" ( half moa)(because 1 moa @200yds= 2" half of that is 1") make sense?
So if your zeroed at 100 and your turret is zeroed to the 0 mark on your turret and your dope tells you you need 26 .5 moa dialed to make the hit you spin 1 full rotation (15 moa) then to 11.5. ( 11.5+15=26.5)this will put point of impact right on point of aim providing all your dope data inputs are correct.
Does this all make sense?

Watch this, it explains it very well, NSSF also has a good vid on mil radians

Most scopes per click is 1/4 moa, so 4 clicks per moa. A lot of scopes i'm familiar with will give you 15 moa per revolution (60 clicks) of the turret. So not sure what your .37 is...but typically you would mount your scope to your rifle, get it zero'd at a desired range. A lot of centerfire hunting rifles zero for 200 yards for example. But you can do this on an air rifle or rimfire also, zero distance quite a bit less of course. To go up 21 moa from your zero you'll be going up 84 clicks, or a full rotation of 15 moa plus 6 more moa (6 moa x 4 clicks per moa = 24 more clicks past the first 15 moa/60 clicks).

For perspective, dialing in 21 moa from a 50 yard zero on a .22 lr rimfire that would take you to 200 yards. Adding 21 moa from a 200 yard zero on a typical centerfire cartridge it would get you to 775 yards. Hope that helps.

Your 0.37 MOA is one and a half clicks, based in 0.25 moa per click. To acy get that you could dial one or two icks and split the difference. For 21 MOA, assuming the standard of 0.25 per click, it would be 84 clicks.
As mentioned, watch the above videos and the Natiknal Shooting Sports videos with Ryan Cleckner. As a matter of fact, just search Ryan Cleckner on YouTube. His experien e and ease of expiration is great.

Or check out mil scopes. 0.1 mil per click. 10 clicks per mil. a 0.1 mil click is slightly larger movement than 0.25 moa click though, so some people dont like it for precision target adjustments. Depends what you need. Precise clicks, or easy decimal converting to clicks in your head. Is this for hunting or for target shooting? What distances are you planning for?
