Figure 1: CoordTransform converts coordinates from latitude/longitude to Universal Transverse Mercator (UTM) or vice-versa. Just enter the coordinates in the appropriate boxes and press the appropriate button. When converting from UTM to lat/long, make sure you include the UTM zone and hemisphere for those coordinates.

The program supports 58 ellipsoids for the datum, but unfortunately can’t convert from one datum to another; hopefully, this will be added in a future version.

decimal sexagesimal

Figure 2: Program will supposedly accept input in both decimal and sexagesimal (degree-minute-second) format. In the latter, it will be converted automatically to decimal, handy just for that purpose.

Other issues: One fairly substantial bug – it won’t accept or calculate negative values in sexagesimal mode correctly. Author has been informed by comment, and this should be easy to fix.

Final thoughts: If you’re dealing with decimal degrees only, or sexagesimal in the northern half of the Eastern Hemisphere, it’s a useful app as-is. Otherwise, you’ll need to wait for a bug fix.
