one minute of angle is equal to 1/60 of a degree.
bit of trig here
sin of one minute x 300 feet = 0.0002909 x 300 = 0.087 feet
one inch = 1/12 foot = 0.0833 feet
so minute of angle is a blond cnut hair over 1 inch at 100 yards, a half inch at 50 yards 2 inches at 200 yards and so on

When reading scopes, I'm guessing you're refering to adjustment knobs? If so, they usually talk about being 1click=1/4 MOA, therefore one click is approx 1/4 of an inch in whatever direction the scope was adjusted in when looking at something 100 yards away. Some scopes have even finer adjustments, but most of mine have 1/4 MOA adjustments.
When someone says their rifle shoots MOA, they mean it groups several shots in (approx) one square inch at 100 yards.
Hope this helps
Cheers, Al

MOA is also called Minute Of Arc.
BTW, 1 MOA wasn't designed to be approx 1" at 100 yards, it is just a coincidence...... The reason everyone is saying "approximate" is that 1 minute of angle at 100 yards = 1.047 inches.
Degrees of arc
Minutes of arc
Seconds of arc
have all been used for hundreds of years in surveying and navigation.

1 MOA is what everyone on the internet shoots with an out of the box Savage, Remington, Stevens using Winchester white box ammo or surplus ammo. Usually in a gale force wind, shooting off the stacked up 2X4's with indoor-outdoor carpeting stampled to it. (found on evey range in Canada)
These MOA angle rifles and ammo are rarely ever found on the range during competitions.

Or during hunting season
I shoot M.O.M all the time ....

I think we all need to stop shooting at extinct, flightless birds...
It is really not cool.
http://en.wikipedia.org/wiki/Moa
The moa were eleven species (in six genera)[5] of flightless birds endemic to New Zealand. The two largest species, Dinornis giganteus and Dinornis novaezelandiae, reached about 3.6 m (12 ft) in height with neck outstretched, and weighed about 230 kg (510 lb).

Read up on it dude it is one of the foundational mathimatics that helps you understand bullet flight ! Basic it is a measurement if you fire 3 rounds at 100 yards and from center to center they measure 1 inch that shot group was 1 MOA theory if those same bullets would have flown 1000 yards and hit the target they would have a 10 inch center to center print on the target ,typically one click on your scope will move your point of impact 1/4 of an inch in the direction indicated on the scope turret , have fun wraping your brain around this

^^ Good one. For the people who have figured this out, it is wonderful - for them. For the rest of us - 1" group at 100 yds, something even the commoners can relate to. Sort of like the guys whose vehicles use 10l/100km (just an example) instead of 20 mpg.
Flamers: save your time.
