Who says the KM grids should be all of the exact same size? Or aligned to the same degrees? It is more appropriate for the KM to align those grids to actual shorelines. There's no point in having halve of a grid covered with real-estate where you can't swim.
In any event if you measure the distances of several cities or shoreline-features to the Greenwich meridian and equator you'll see that 120km number appear quite accurately once you divide the lengths by the actual lattitude/longitudes in Google Earth for example..
