I'd recommend just using a simple function for this particular thing, and then use proj4 for complicated geographical transforms. This is such an elementary operation it's not worth getting involved proj4, which, as far as I'm aware, doesn't bother doing what you're wanting anyway.
Now, proj4. What other sorts of transformations are you likely to be doing? Do you know the ins-and-outs of projections and datums? If not, you'll really need to learn something about these in order to use proj4 correctly.
