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)
