This program converts the latitude and longitude between
the prefixs of UK postcodes. It also gives u the Northing
and Easting of the start from postcode, if u require the
destination Northing and Easting enter it as start postcode.
I sold my cab/courier app sometime ago and it contained
a mileage calculator that was not so good but it helped.
This version is near enough for a rough estimate, as 2
nearby postcode prefixes can be next door for example
W1 and W2 in London then u may get the 3.6 miles for
a 5 yard distance that would not be correct, It would be
however for a courier or taxi it would be minimun charge.
I took the lat long from the middle of the postal district.
It also allows for extra mileage hills curves and so on.
Test a known mileage and let me know pretty please.
