My confusion is that I have some formulas to plug in these values, but it
seems to me that if I use the wrong set of data, my zipcodes will be wrong
too. I also don't understand why there is even such a difference. I can
understand a few decimal points being different, but I don't understand how
they are positive and negative, when it's supposed to be based upon the
equator and the prime meridian. Since they're US zipcodes, it's not like
we're in different parts of the world or anything.
