It is possible to count latitude delta (and longitude delta) from
given distance in meters in Google Maps API?

I've done it with approximate function given below:

function translateDistanceToDeltaLatLng(distance: Number): Object {
        var deltaLat: Number = (distance * 180) / 20000; //20000 - half of
Earth circumference
        var deltaLng: Number = (distance * 360) / 20000;
        return {lat: deltaLat, lng: deltaLng};
}

Is there a Google API function which can do better without
approximation?
