will be helpful for those in need If you're looking to use the v3 google maps API, here is a function to use: Note: you must add &libraries=geometry to your script source

<script>
var p1 = new google.maps.LatLng(45.463688, 9.18814);
var p2 = new google.maps.LatLng(46.0438317, 9.75936230000002);

//calculates distance between two points in km's
function calcDistance(p1, p2) {
}

</script>

## Is there any available API to represent various units of item like KG, Litre, Metre, KM, etc

hop of those help? First of all, you should really learn how to use pattern matching, and use it instead of List.hd and List.tl operators. It is also a bad idea to pass tuples to functions, instead of passing multiple arguments.
For example, the addLists function, which you define as
let rec addLists = function (alist, blist) ->
if((alist == []) && (blist == []))
then []
else List.hd alist +. List.hd blist::addLists(List.tl alist, List.tl blist)
let rec add_lists xs ys = match xs,ys with
| [],[] -> []
| x::xs, y::ys -> x +. y :: add_lists xs ys
| _,[] | [],_ -> invalid_arg "add_listss: lists are of different lengths"
if cond then it_is_square else it_is_cube
let rec hopTrain = function (allStates) ->
if((allStates == []))
then[]
else if((List.tl allStates == []))
then [hopTrainAstate(List.hd allStates)] (* if only one state then output that state *)
else hopTrain3(hopTrainAllStates(allStates), hopTrainAllStates(allStates));;
type row = {row : float list}
type matrix = { rows : row list}
type weights = { weights : matrix}
