Milliradian Distance Calculator

Formula

The formula to calculate the Milliradian Distance (Dm) is:

$Dm = \frac{S \times 27.8}{mrad}$

Where:

$Dm$ is the milliradian distance (yards)
$S$ is the size (inches)
$mrad$ is the milliradians (mils)

What is Milliradian Distance?

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.

Example Calculation

Let's assume the following values:

Size (S) = 18 inches
Milliradians (mrad) = 3.5

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.
