It sounds as though your requester may not be knowledgeable about the
terminology. I recommend providing both latitude/longitude and
utmzone/easting/northing.
GeographicLib's GeoConvert can do the conversion for you as in
echo 45N 75W | GeoConvert -u
18N 500000 4982950
(GeoConvert is pre-wired for WGS84.)
