Milliradian Distance Formula:
| From: | To: |
The milliradian distance calculation is used to determine the distance between two points based on their size and angular measurement in milliradians. This formula is particularly useful in fields like surveying, ballistics, and optics where precise distance measurements are required.
The calculator uses the milliradian distance formula:
Where:
Explanation: The formula calculates distance by dividing the actual size of an object by its angular size in milliradians, then multiplying by 1000 to convert to meters.
Details: Accurate distance calculation using milliradians is essential for precision targeting, surveying applications, and optical measurements where direct measurement is impractical or impossible.
Tips: Enter the actual size of the object in meters and the angular measurement in milliradians. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is a milliradian?
A: A milliradian (mrad) is one thousandth of a radian, which is a unit of angular measurement. There are approximately 6283.185 milliradians in a full circle.
Q2: How accurate is this calculation?
A: The calculation is mathematically precise when accurate measurements of size and angular measurement are provided. Accuracy depends on the precision of input values.
Q3: What applications use this calculation?
A: This calculation is used in military targeting, long-range shooting, surveying, astronomy, and any field requiring distance estimation through angular measurement.
Q4: Can I use different units of measurement?
A: The formula works with consistent units. If you use different units for size (e.g., centimeters), you'll need to adjust the calculation accordingly.
Q5: Why multiply by 1000 in the formula?
A: The multiplication by 1000 converts the result from kilometers to meters, as the basic formula (Size/mrad) gives distance in kilometers when size is in meters.
