Has anyone tried to work this out? All I'm trying to get is the rough distance in miles between two UK postcodes using Google Maps API for a basic auto quote script based on mileage travelled. I thought it would be easy but it seems that I need to convert each postcode to Lat/Long using Geocoding and then work it out from there. I can't find any examples so before I find another way of 'skinning the cat' has anyone had experience of this and able to point me the right way? TIA
