Target size and mil reading
This uses distance = target size in meters × 1000 / mils. One mil is treated as a thousandth of a radian approximation.
Estimated range
900 m
0.9 km
Height in meters
1.8
Range in kilometers
0.9

Formula

distance = target size (m) * 1000 / mils

The calculator assumes a standard mil reading. If you enter feet, the value is converted to meters before the range is computed.
