This compact map scale is designed to use with USGS maps, which use the UTM coordinate system. At only 2.75 inches square, the UTM map scale can fit in your pocket or in your compass case with your compass. Or use the corner lanyard hole to slide this scale onto your lanyard with your compass.
The perimeter of this protractor scale features 0-360 degree grid lines, graduated every one degree. On the interior are corner grids scales for 1:24,000 km, 1:25,000 km, and 1:50,000 km. For reference, the most common 7.5 minute USGS topo map features a 1:24,000 scale in kilometers.
