Get distance between two place in google map

Here I am postting little code for get distance between two place in google map.
We need only latitude and longitude of both place and using this we can get by-road distance between them.

var currentLocation = new google.maps.LatLng(currLatitude,currLongitude);
var service = new google.maps.DistanceMatrixService();
var distance = 0;

var destinationLocation = new google.maps.LatLng(destiLatitude,destiLongitude); service.getDistanceMatrix({
origins: [currentLocation],
destinations: [destinationLocation ],
travelMode: google.maps.TravelMode.DRIVING,
avoidHighways: false,
avoidTolls: false
},
function( response, status ) {
    if (status == google.maps.DistanceMatrixStatus.OK ){
distance = response.rows[0].elements[0].distance.value ;
    }
});

Here you get distance in km.
If you want to convert it into miles you can use below line.

var distanceInMiles = Math.round(( (response.rows[0].elements[0].distance.value /1609.34)*100)/100);
