google api return kilometers instead of miles

I have an application to calculate distance between two points.

https://maps.googleapis.com/maps/api/distancematrix/json?origins=" + origins + "&destinations=" + destinations + "&units=imperial...

I am setting the units to imperial , however some distances are returned in Kms and Ft. Do I need to set any other parameter?

Use unitSystem: google.maps.UnitSystem.METRIC if you want result in Kilometers. Use unitSystem: google.maps.UnitSystem.IMPERIAL if you want result in Miles.

$(document).ready(function(){
    var distanceService = new google.maps.DistanceMatrixService();
     distanceService.getDistanceMatrix({
        origins: ["10 West 35th Street, Chicago, IL, USA"], //$("#autocompleteDeparture").val()
        destinations: ["Union Station, South Canal Street, Chicago, IL, USA"], //$("#autocompleteArrival").val()
        travelMode: google.maps.TravelMode.DRIVING,
        unitSystem: google.maps.UnitSystem.IMPERIAL, //use "IMPERIAL" for Miles, "METRIC" for KMs
        durationInTraffic: true,
        avoidHighways: false,
        avoidTolls: false
    },
    function (response, status) {
        if (status !== google.maps.DistanceMatrixStatus.OK) {
            console.log('Error:', status);
        } else {
            console.log(response);
        }
    });
});

Here is the code I used to get the distance in miles.

Method 1:
You will have to call the google map api JS library with your key then use this below code.

var origin1 = new google.maps.LatLng(55.930385, -3.118425);
var origin2 = 'Greenwich, England';
var destinationA = 'Stockholm, Sweden';
var destinationB = new google.maps.LatLng(50.087692, 14.421150);
//var  uniteSystem = 'IMPERIAL';
var service = new google.maps.DistanceMatrixService();
service.getDistanceMatrix(
  {
    origins: [origin1],
    destinations: [destinationA],
    travelMode: 'DRIVING' ,
    unitSystem: google.maps.UnitSystem.IMPERIAL   
  }
  , callback);

function callback(response, status) {
  // See Parsing the Results for
  // the basics of a callback function.
  console.log(response);
}

You will have an array of element as response.

Method 2: This is the url method I used to get the distance in miles. https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=40.6655101,-73.89188969999998&destinations=41.43206,-81.38992&key=TOUR_API_KEY

Remember to change the API key.

The distance.text field is expressed in the units passed in the request; the distance.value field is always expressed in meters.

Refer to the Distance Matrix developer guide and you'll find this blurb:

Note: this unit system setting only affects the text displayed within distance fields. The distance fields also contain values which are always expressed in meters.
