What it means
How much does it cover?
The scale is exact only where the map projection is true. On a small-scale map of a whole country, the printed scale is a nominal figure.
The math
How to convert cm/km to 1:N
Everything comes from the denominator: cm per km = 100,000 ÷ scale, meters per cm = scale ÷ 100, and inches to the mile = 63,360 ÷ scale.
Example: 25,000 cm/km = 4 1:N.
