0.25km/cm
That's about the same as a walking map. A 40 cm wide sheet at that scale covers about 10 km across.
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 1:N to km/cm
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 1:N = 0.25 km/cm.
