Getting the distance between two Geo points in miles or kilometers is as simple as changing the “unit” query parameter of your request to “kilometers” or “miles”.

Example

To get the distance in kilometers

req.query({
“start_point”: “(42.335321,-71.023516)”,
“end_point”: “(47.373535,8.541109)”,
“unit”: “kilometers”
});
