The formula to calculate the Milliradian Distance (Dm) is:
\[ Dm = \frac{S \times 27.8}{mrad} \]
Where:
Milliradian distance (mrad) is a measure used in ballistics and shooting to estimate the distance to a target. It is based on the size of the target in inches and the angle in milliradians (mils). The milliradian system is widely used in the military and by marksmen for accurate range estimation and targeting.
Let's assume the following values:
Using the formula to calculate the Milliradian Distance (Dm):
\[ Dm = \frac{S \times 27.8}{mrad} = \frac{18 \times 27.8}{3.5} ≈ 143.14 \text{ yards} \]
The Milliradian Distance (Dm) is approximately 143.14 yards.
