<p>Hello,</p>
<p>maybe you should first figure out what is the input system exactly? what is the input ellipsoid and datum .. then figure out what is the output system exactly (ellipsoid is WGS84, but does it have any datum, maybe WGS84 also) .. then use cs2cs .. since you have no projection in either side you can use proj=latlong as a pseudo projection .. (somebody else might be better to explain how cs2cs exactly works) .. see also:</p>

<div dir="ltr">Dear Proj list members:<br /><br />Being a very new in this field, could someone answer me about the following problem:<br /><br />I have a pair of Geodetic Latitude and Geodetic Longitude (50.89524, 117.69043).<br />How can I convert it into Latitude and Longitude with WGS84 Ellepsoid?<br /><br />Thanks in the advance.<br /><br />Artur</div>
