The following code returns the distance between to locations based on each point’s longitude and latitude. The distance returned is relative to Earth’s radius. To get the distance in miles, multiply by 3960. To get the distance in kilometers, multiply by 6373. Latitude is measured in ...

Users of our US Zip Codes, US Cities and World Cities databases often need to calculate the distance between two geographic coordinates (in lat/lng). Since the earth is a sphere, you can't use the distance formula that works for two points in a plane. Instead, you should use the Havers...
