Convert gps coordinates to 4000+ different coordinate systems, both projected and geographic, covering the whole world ( local systems, deprecated systems, almost every system ever used anywhere ).

Cassini-Soldner, used in Italy, are implemented too. SUPPORT FOR GAUSS-BOAGA NOT RELIABLE, i'm currently working to fix it

Simple to use:
Select your target coordinate system and locate point in the map, below you can read coordinates in wgs84 ( map default ) and target coordinate system too ; to locate and translate current position, use GPS button

You can save points and then export them in a csv file

( warning: many coordinate systems are valid only in limited geographic zone, you will see dashes if translation is not possible for the current point )

This app does not accurately display Massachusetts state plane coordinates in the nad83 feet format. Not even close.
