Lat Longs to Miles

[ObsidianWolf]

Im wondering if anyone knows the conversion for Lat Longs to Miles.  Im working with it some in a program, but im still a bit hazy.  Any help would be greatly appreciated.

Here what Im currently using, but It isnt giving me the data that I want...and Im in no way a Math favoring man.

Code Select Expand


DistanceinMiles = (((LatDiff ^ 2) + ((LongDiff * Cos(LongCenter * (22 / 7) / 180)) ^ 2)) ^ 0.5) * 60 * 1.852 / 1.6093



update, spelled distancewrong

The formula you've given is very unclear. You're using obscure constants such as 1.852 and 1.6093, without explaining what they mean.

You should give constants names, i.e.:

Code Select Expand


Const Blah = 1.852

Also, 22/7 is a bad approximation for Pi. I suggest just explicitly writing 3.14159 or something to that effect.
