If that's what you want, then the formula given will work. If you're
XYZ system is something else (e.g. UTM), you need a different formula.
If this is the case, find out what coord system your XYZs are in, and
email me with that info, and I can probably give you the conversion
formulae or source code.

That depends on what coordinate system XYZ is in. The other answers so far posted are assuming you want to go from lat/long to geocentric (aka Earth-Centered Earth-Fixed) coordinates. (i.e. 0,0,0 is the center of the Earth).
If that's what you want, then the formula given will work. If you're XYZ system is something else (e.g. UTM), you need a different formula.
