How is distance measured in navigation?
Distance is measured on the latitude scale, at the sides of the chart. One minute of latitude is one nautical mile-at that latitude. One nautical mile is 1852 metres. One minute is one nautical mile (M) at that latitude because on Mercator Projection charts the latitude scale increases the further north you travel.
