WALT Calculator

WALT Calculator is a toolbox containing many useful weather, location, and target related computations.

WALT: Weather, Altitude, Lat/Long, Target

Features:

1. Density Altitude Calculator Great for pilots, shooters, or weather enthusiasts, the WALT's density altitude calculator can provide a useful meteorological metric for comparing performance in differing weather conditions. For devices with a pressure sensor (iPhone 6 and later), DA can be automatically calculated from the device's own pressure sensor.

2. Field Elevation Calculator Know the ambient/station pressure and the alimeter setting/barometric pressure? Calculate your elevation above mean sea level with this calculator. Know your elevation but not your ambient pressure? With the field elevation calculator, you can calculate any of these three metrics!

3. Geographic Coordinates Converter Convert a geographic location from degrees, minutes, and seconds into decimal degrees, decimal minutes, or UTM.

4. Geographic Distance Calculator Find the distance between two points on the globe, given a set of geographic coordinates.

5. Target Calculator Designed primarily for shooting sports, the target calculator can compute distance to target, given target size and angle. Or target size, given target distance and size. This is a great complement to a mildot or MOA reticle optic.
