Binoculars Range Calculator
Calculate distance to objects using binoculars with reticle measurements and known object heights
Calculate Distance to Object
Known height of the object you're observing
Angular size as measured on binocular reticle
Distance Calculation Results
Formula used: d = h × 1000 / Mil
Where: d = distance (km), h = object height (m), Mil = angular height (mrad)
Input values: Height: 0.0m, Angular: 0.0 mrad

Understanding Binoculars Range Finding
What are Binoculars?
Binoculars consist of two telescopes mounted side-by-side and aligned in the same direction. They allow stereoscopic vision, providing depth perception and a three-dimensional image. Many military and surveying binoculars include reticles for range estimation.
Milliradian (Mil) System
- •1 milliradian = 0.001 radians
- •1 meter appears as 1 mrad at 1 kilometer
- •Simple ratio for distance calculation
- •Widely used in military applications
Range Formula
d = h × 1000 / Mil
- d: Distance to object (kilometers)
- h: Object height (meters)
- Mil: Angular height (milliradians)
- 1000: Conversion constant
Example: A 6m house appearing as 1 mrad is 6 km away
Applications
Military
Target acquisition, artillery spotting, reconnaissance missions
Surveying
