how much is 1 mrad at 1000 yards?
You see that the fence post spans 2 mils (mrads). Convert the 36-inch fence post height into yards and use the formula to calculate the distance to your target. In this case, your coyote is at a distance of 500 yards. 1 mil (mrad) will subtend 1 yard at 1,000 yards or 1 meter at 1,000 meters.
