CALCULATING SIZE (HEIGHT AND WIDTH)
Using the simple formulas below, you can
effectively determine the size of a target if
the distance to the target is known.
For example:
You are 300 meters away from a tank that
measures 15 miles tall and 20mils wide and
you want to know the size of the tank.
Range (Yards) x Measured Mils
1000
= Target size (Yards)
Range (Meters) x Measured Mils
1000
= Target size (Meters)
300 (Meters) x 15 Mils
1000
= 4.5 Meters tall
300 (Meters) x 20 Mils
1000
= 6 Meters wide
Range (Yards) x Measured Mils
27.8
= Target size (Inches)
