New scope has me confused

To add further to the confusion: 1 cm does NOT equal .36 inch, as many have stated on this thread.
1 cm = .3937 inch (1 cm/ 2.54 cm/inch). I usually round it to .4 inch for practical purposes, and would think it would suffice for OP's distances he wants to shoot.
Nonetheless, after entering his starting data into a ballistic calculator, he should true his ballistics by verifying the drop of his bullets at the different distances he wants to shoot (as has been stated so many times by members of this forum). Only then will he have a reliable DOPE chart.

Thanks for clarifying the cm to inch conversion....What my scope says, and what I was trying to get across, was this: My Leica scope is a Mil scope and each click equals 1cm at 100 METERS. Converting that to an MOA scale (using inches and yards) would mean each click equals .36" at 100 YARDS.
I'm not a Mil guy, I understand it marginally, but have always thought of distances and scope adjustments in inches and yards. So equating the value of each click in inches juxtaposed with the distance in yards just goes together for an old MOA guy like myself.....and probably most others that have always used that scale.

But the scopes move .36" at 100 yards and 1cm at 100 meters.
 
This thread is making my head hurt.

DONT LAUGH this is my first go round on this Mil stuff. Bought this last week and im fairly confused now. All my Swarvosky scopes have inch incroments and this thing has mils? it is super clear and bright at night and I have it sighted in at 100 dead center at the zero stop now. How many "clicks" (roughly) will I need for 2,3,4 and 500 yards? I need a good website link to figure this out. Ill make a chart after I figure it out. Gun is a short 16.5" 6.5cm shooting 100gr varmint bullets. No idea how fast they are. I haven had time to put the magneato speed on it yet.

VX-5HD 3-15x56 CDS-ZL2 Side Focus Metric Illum. FireDot 4 Fine

Let there be light! The VX®-5HD 3-15x56mm gives you all the flexibility of its 44mm counterpart, but with the 56mm objective bell, it maximizes as much exit pupil light as your eye can handle. From the mountains, to the open plains, and to range day, this scope has the ability to dominate them all.

Did you ever get anywhere?
 
Great when the scope has a real mil dot reticle & .1 mil click values. At 500 yards 1 mil will cover 18 inches, at 250 yards 9 inches at 100 yards 3.6 inches & the numerous reticle features such as dot width, distance between dot edges, distance between dot centers & so on can be used to estimate ranges provided scope power in a 2nd FP is set to represent those values.

Calculations are simple-- 100 yards = 36 * 100 = 3600 = inches in 100 yards 1 mill is 1/1000 of whatever so 3600/1000 = 3.6 inches per mil at 100 yards. Lots of objects out there are close to 18 inches, so 36 * 500 = 18,000 inches per 500 yards, then 18,000/1000 = 18 inches per mil at 500 yard, or spanning the centers of 2 reticle dots.

100 meters = 100 * 100 cm = 10,000 cm in 100 meters, 10,000/1000 = 10 cm per mil at 100 meters, 1 inch = 2.54 cm, 10 cm/2.54 = 3.94 inches per mil at 100 meters. 1 yard = 36 inches, 1 meter = 39.37 inches. A .1 mil click value will get 1 cm at 100 meters.

Metric seems to be more simple but most of us think in yards & inches. A 46 cm wide object is about the same as an 18 inch wide object making my head hurt......

Then there are NATO & other standards.

So, what is that with a MIL dot reticle and 1/4 MOA turrets? What is hte math formula? Distance between dots, etc get to inches, etc. Right now I guesstimate and see where the bullets hit and when it gets where I want - stop. Not very easy to do on the fly and hoping what I am shooting at stays put till I hit it....
 
A Mil reticle/Moa turrets is called a piece of junk. The smart thing to do is spend the money and buy a mil/mil or moa/moa with the scale reticle. No figuring needed. You can always find your approx holdover, shoot, use the reticle scale to find the difference in your POA and your POI, dial the turret and you're done. Period. No math/figuring needed.

Check this video out, he gives a good explanation.

1cm = 10 mm, or 1mm = 10th of a cm.

and I will skip decimeters LOL

PS: I use MOA scopes exclusively. Too old to change..

A poster to a thread should read what he wrote before posting!
Spelling 101
'mm' is not an abbreviation for 'meter'
To The Oregonian, you must be an editor. LOL
