You can convert degrees of latitude / longitude to meters in your head var R = 6378.137; // Radius of earth in KM var dLat = (lat2 lat1) * Math.PI / 180; var dLon = (lon2 lon1) * Math.PI / 180; var a = Math.sin(dLat/2) * Math.sin(dLat/2) + Math.cos(lat1 * Math.PI / 180) * Math.cos(lat2 * Math.PI / 180) * Math.sin(dLon/2) * Math.sin(dLon/2); var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 a)); var d = R * c; return d * 1000;
