How to create a LatLngBounds around a LatLng point with a distance in meters?

Question

I would like to create a square (LatLngBounds) around a central point (LatLng) at X meters.

Answer 1

Use the L.LatLng.toBounds() method, e.g.

var center = L.latLng(40,-3);
var bounds = center.toBounds(500);

or

var bounds = L.latLng(40,-3).toBounds(500)
