I was unsure whether the OP was able to do coordinate conversions in principle and just didn't know how to access spherical mercator, or whether he didn't know how to use these tools at all? Anyway, epsg:900913 is somewhat picky in choosing its friends. Sometimes a tender echo "<3785> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgri...@null +no_defs <>" >> /usr/share/proj/epsg helps, but I'm unsure about the equivalent of this on Windows (which the OP seems to be using).
