US commercial territory and radius mapping
In US real estate and logistics, radius search rings (e.g. 1-mile, 3-mile, 5-mile rings) are standard benchmarks for demographic analysis and commercial site selection.
Each 1 square mile represents exactly 640 acres, making acreage conversions straightforward for land development.
Worked example: 10-mile trade area
A 10-mile radius ring encloses 314.16 square miles (201,062 acres) with a 62.83-mile perimeter.
Driving time from center to edge averages 19 minutes at typical 31 mph suburban transit speeds.
