The Centre of London

Where is the centre of London? Distances from London are measured from Charing Cross, specifically from a traffic island immediately to the south of Trafalgar Square. Is this the true centre?

In mathematics and physics, the centroid, also known as geometric centre or centre of figure, of a plane figure or solid figure is the arithmetic mean position of all the points in the surface of the figure.
In geography, the centroid of a radial projection of a region of the Earth's surface to sea level is the region's geographical centre. (Wikipedia)

The outer boundary of Greater London forms a single shape. The centre of this shape is on Baylis Road SE1: Latitude 51.500538, Longitude -0.111019.
