Best Answer

The answer depends on how closely you look at it. On the macroscopic level you could simply measure the length of ocean, lake, and river coastline as given on a world map. On a microscopic level the length becomes almost fractal-like with each particle having some additional participation in the length. At this scale the length approaches infinity.
