Angle to inches
1 MRAD is 3.6 inches per 100 yards. 1 MOA is 1.047 inches per 100 yards. 1 MRAD is about 3.438 MOA.
Range from your reticle
Yards = size in inches × 27.78 ÷ mils, or × 95.5 ÷ MOA. A 18 inch plate that fills 1.5 mils is about 333 yards. Accuracy depends on how well you read the reticle.
Slope angle (shoot-to range)
Rifleman's rule: shoot to the horizontal distance, range × cosine of the angle. Uphill and downhill shots both hit high if you dial the line-of-sight range. This is a good approximation under about 30 degrees; use the Precision Calculator's slope input for steeper shots.
Turret clicks
Match the unit to your turret. A true 1/4 MOA click moves the impact about 0.26 inch at 100 yards. Some scopes use a 1/4 inch at 100 yards click instead (about 0.24 MOA), so check your manual.
