Mille: a French mile, cited up to the 1930s. On a military chart, 2 cm = 1 km, and 3.7 cm = 1 mille, thus 1 mille is equivalent to 1.8 km or 1800 metres. 1 metre = 39.375 inches . Thus 1800 m x 39.375 (inches) divided by 12 , then 3, then 1760 gives a French Mille as being 1.1186 English Statue miles: which might be equivalent to a Nautical Mile or “mile at sea” in naval parlance. SGM Maps may therefore be citing km for the land and nautical miles for the hydrography. Italy used its own mile until after the war, which might also be that recorded on a SGA chart which includes the Italian border. An English mile is 1609 metres.
