I don't know about what approximations you will use, but your gold standard (enshrined by law in Australia and probably many other countries) is Redfearn's formulae for WGS84 <=> UTM. They are accurate to literally atomic dimensions. Geoscience Australia[^]has a good discussion of all this sort of stuff on its website, and includes Redfearn (and other transformations) as Excel spreadsheets for free download. There are online convertors too. Google Redfearn and take it from there.
[edit] forgot shameless plug. For a 'real world' application of Redfearn, have a peek at gridlle.no-ip.org[^] Also added GA link. [/edit]
