That depends if it's latitude or longitude. East/West there is no fixed amount, as circles of latitude are smaller as you approach the poles. For the longitudinal circles(north/south) 1 minute of arc is almost exactly one (int'l) Nautical Mile which is 1,852 meters. [1 degree of arc is 60.1 Nautical Miles since the world's circumference is (roughly) 21639.007 NM] Of course East/West is the same, if you're on the equator.

I'm sure there's a clever formula somewhere that takes the latitude issue into account, but I don't know it. HTH.
