Product Description

The 1:31,680 scale represents a distance equivalence of 1 inch = 1/2 mile. When I created this tool, I had the McKenzie Boundary Waters maps in mind. Since then I've discovered that Halfmile's pdf maps of the Pacific Crest Trail also use this scale, have a 1km UTM grid on them, and are a great match with this tool.
