A scale of 1:N compares equal units. One map cm represents N ground cm. Convert centimeters to meters by dividing by 100; do not compare a map centimeter directly to a kilometer. These are ideal flat maps.

Worked example

At 1:5,000, 2 map cm represents 10,000 ground cm, or 100 m.

A four-division scale bar labels 0, 2, 4, 6 and 8 km. Each nominal one-map-centimeter division represents two kilometers. The on-screen size is not guaranteed to measure four centimeters.
