[Proj] Converting to WGS84 Latitude/Longitude

It could be the same thing. "Geodetic" latitude is the same as ordinary,
everyday latitude. There are some other flavours of latitude as well,
auxiliary latitudes that are mainly used to simplify some kinds of
computations, but "geodetic" is the ordinary kind.
For longitudes, there is only one flavour, but the zero meridian is
not always Greenwich.
So the coordinates you mention could be in WGS84 Lat/Long already.
But it is not certain, since they could be expressed in some other
geodetic datum that uses a different ellipsoid.
Do you have any documentation about the geodetic datum of your
coordinates (like Pulkovo 1942, Pulkovo 1995, PZ 1990, or WGS84),
or about the ellipsoid used?

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