It is called the scale.
Another name for a map legend is key.
You can measure a curved line on a map by using a string or measuring tape to match the curve and then measuring the length against a ruler or a map scale. Alternatively, you can break down the curve into smaller straight line segments and then add up their lengths to get an estimate.
The Key, or Legend, or a map gives a list of the symbols used on the map and what they represent. There is a fairly standard set of symbols used for different types of map so that anyone looking at the map can understand what it is being shown. For example, on a weather map a cold front is shown as a black line with semi-circular bumps (in blue if coloured), a warm front is shown as a black line with triangles (in red if coloured) and an occluded front is shown as a black line with alternate semi-circular bumps and triangles.
Another name for a relief map is a topographic map. These maps use contour lines to show the elevation and shape of the terrain, allowing the reader to visualize the three-dimensional landscape on a flat surface.
you use a map scale by measuring by inches

The measuring line is one of a group of symbols -- or keys -- used in mapping to provide rich information using small and accessible icons.Specifically, this line is called the scale.
