Questions about this tool
How many NATO mils are in one degree?
1 ° = 17.7778 mil exactly.
How do I convert degrees to NATO mils?
Use mil = ° × 17.77777778. For example, 25 ° = 444.444 mil.
How many degrees are in one NATO mil?
1 mil = 0.05625 °.
Why does my calculator give a strange answer for sine?
It is probably set to radians (RAD) while you are entering degrees. The sine of 30 degrees is 0.5, but the sine of 30 radians is about -0.988, so switch to DEG first.
What is the difference between MOA and MIL on a rifle scope?
MOA is an arcminute, 1/60 of a degree, while a MIL is a milliradian, about 3.438 MOA. At 100 meters a 0.1 MIL click moves impact 1 cm, and 1 MOA moves it about 2.9 cm.
