Comment convertir un groupement en MOA ?

Divide the group size in centimeters by 2.91, then divide by the distance in hundreds of meters. For example, a 3-centimeter group at 100 meters is approximately 1.03 MOA.

Qu'est-ce qu'un bon groupement en MOA ?

A weapon classified as "sub-MOA" has a group of shots that fits within less than 1 MOA—that is, less than 2.91 cm at 100 m. In precision shooting, aiming for 1 MOA or less is a common goal.

Why Measure Your Project Management Team in MOA?

A measurement in centimeters means nothing without the distance: 3 cm at 50 m and 3 cm at 200 m do not represent the same level of accuracy at all. By converting it to MOA (minute of angle), you get a measurement that is independent of distance and therefore comparable from one shooting session to the next.

1 MOA ≈ 2.91 cm at 100 m. A group smaller than that is called "sub-MOA."
1 MIL = 10 cm at 100 m.
The 100-meter equivalent brings your group to a single reference distance.

Real-world example

A 30 mm (3 cm) group at 100 m is worth about 1.03 MOA: your rifle and ammunition are practically “sub-MOA.” The same 3 cm group at 200 m would be worth about 0.52 MOA—twice as accurate.
