# 1:24,000 Is an Example of What Kind of Scale?

Usgs topographic maps have been published at many scales, but 1:24,000 (also referred to as a 7.5-minute quadrangle) has been the standard topographic map scale since 1947.

## 1:24,000 Is an Example of What Kind of Scale?

In cartography, the termscale refers to the relationship between the distance on a map and the corresponding realworld distance.

The most common scale used in topographic maps is the fractional scale, in which the map is drawn at a specific fraction of the realworld distance.

For example, a map with a scale of 1:24,000 means that one unit of measurement on the map represents 24,000 of the same units in the real world.

There are a variety of other scales that are used in different types of maps. For example, a largescale map would have a smaller fraction, such as 1:100,000, while a smallscale map would have a larger fraction, such as 1:1,000,000.

The scale can also be expressed as a ratio, such as 1:24,000, or as a verbal scale, such asOne inch equals two miles.” The choice of scale for a map is determined by its purpose.

A map that is meant to be used for navigation purposes, for example, would need to be largescale so that the user can see the detail necessary for planning a route. A map that is meant to show a large area, such as
