lat/long

[Joe Leone]

Hi,

I'am trying to convert data from lat/long format to UTM
I seem to get different results depending on the conversion program I use and the format that the lat/long is provided.

The lat/long I want to convert is:

117.646439W 31.526952S

My calculation say this equals 117:38:47W  31:31:37S

I've used m.proj and m.ll2u. Here are the results

m.proj					x	y		utm zone
117.646439W  31.526952S		561371.86   13488193.98
117:38:47W    31:31:37S		5400100.89   -22794869.83


m.ll2u

117.646439W  31.526952S		561371.8589...   3488193.99...   -11
117:38:47W    31:31:37S		438632.9113...	 6511803.89...    50
 
m.ll2u would not accept the correct utm zone of 50

Has anybody any suggestion for the differences and/or how to convert from the coordinates?

Thanks in advance
