Right. Good point. So the procedure would be to find two extreme corner points in UTM, hit one of those web calculators, convert *just* those two points to lat/lon, and then for all points in between you linearly interpolate at the level of accuracy required. Fast and easy.
In the event that you can't find a web calculator or you discover some other coordinate grid on a map, it's almost always possible to find some points with known lats and lons and work from there.
