MilDotCalc helps determine the distance to an object by using the Mil relation formula. A mil, or mil-radian, is an angular unit of measure. If one knows the width or height to a distant object being observed with a mil ranging reticle equipped optic (binocular, rifle scope, etc.), then MilDotCalc can provide precise range estimates between the observer and the distant object.

Good range estimation is key when hiking in the wilderness, playing Golf and when doing long range shooting. Range estimation is also used extensively in military, marine and engineering applications.

Features include:

• Target size in mils
• Target size in one of 5 units of measure
• A table to store your own list of target sizes (in your choice of unit of measurement)
• Range estimation using the Flash to Sound technique (which multiplies the speed of sound at sea level by the time interval elapsed between the flash and sound events)

MilDotCalc is available for Microsoft's Windows desktop, Windows Mobile 6.5, Linux, Maemo, Mac OS X, Apple iOS (iPhone) as well as Google's Android:
