[QUOTE="Brad7348, post: 1936913, member: 70334"] Dont confuse mils with metric. Mil is just a short term for milliradian or milradian, or MRAD. .001 radians. (one thou of one radian) which is an SI measurement. Where in degrees we measure a circle at 360 units. In milradians the measurement is a relationship to the radius length along the circle. There are 2 X 3.14 angular radians in a circle. (6.28 total) The length around the circle is 2 X 3.14 X the radius length. (2 Pi R) This could be in inches, feet, yards, CM, MM etc. But if you measure radius in ft or yards then your resulting shift based on the angle in radians is in english measure, not metric. [/QUOTE]
