Leaflet - Convert lat/lng to standard projection - angularjs

Question

How to convert coordinates from Leaflet coordinate system to coordinate system that Google uses (WGS-84?), if the data are in an external file (geojson)?
In example with external geojson file, I've defined coordinates for Paris and Zagreb and I'm looking for solution to transform these coordinates to accurate location :)
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"id": "par",
"properties": {
"name": "Paris"
},
"geometry": {
"type": "Point",
"coordinates": [
48.858093,
2.294694
]
}
},
{
"type": "Feature",
"id": "zg",
"properties": {
"name": "Zagreb"
},
"geometry": {
"type": "Point",
"coordinates": [
45.815399,
15.966568
]
}
}
]
}
There is Proj4js JavaScript library, but I cannot find similar example for this case (with external file).

Answer 1

Your GeoJSon can be used directly by Leaflet without converting the lat/lng.
I use google maps to get GPS lat/lng of some point and use them in Leaflet without conversion.
// Edit
For me Leaflet and Google maps use the same projection.
//EDIT 2
Html :
<div id="map" class="leaflet-container leaflet-fade-anim"></div>
JS :
var map=L.map( "map" ,{
center:[0,0],
zoom:1, minZoom: 1 , maxZoom:18
});
var base_maps = [];
var layer_OSM = new L.TileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
noWrap: true,
// continuousWorld: true,
attribution: '© OpenStreetMap contributors',
unloadInvisibleTiles: true
});
base_maps['OpenStreetMap'] = layer_OSM;
map.addLayer(layer_OSM);
var markersLayer = new L.FeatureGroup();
var marker = L.marker([p_lat, p_lon]);
markersLayer.addLayer(marker);
map.addLayer(markersLayer);
