A milliradian (occasionally referred to as a mil) subtends one thousandth of a radian. When applied to a distance of 100 meters, one milliradian corresponds to a linear distance of 0.1 meters, or 10 centimeters. This angular measurement, coupled with a known distance, facilitates precise adjustments, particularly in fields requiring high accuracy.
This principle provides a practical and efficient method for ranging, targeting, and making precise adjustments in various applications. Its origins lie in the need for accurate indirect fire calculations in artillery. The milliradian’s utility extends beyond military applications, finding relevance in surveying, long-range shooting, and other fields where precise angular measurements are essential. The systems simplicity allows for rapid calculations without specialized equipment.
