If it was an old map the grid might have related to miles. Newer maps are in kilometres. If the map is over printed with the new grid it helps to standardise it. The features of the area/map have not changed - just the convention of the grid used.

The last answer is reasonable. However it also possible that the map you are referring to is not English. Luckily we have the a single organisation "Ordnance Survey" that has compiled i believe all the maps of the UK. Whilst working in France i found myself having to deal with three sets of grid lines and coordinates, 1 originally compiled for the Imperial Regime, one for the Napoleonic and a new version trying to standardise. Also in War zones maps are often made inaccurate on purpose as I'm sure any one will know who has tried to navigate through the Troodos in Cyprus.
