1 US survey mile = 5,280 US survey feet

1 square mile (US survey) ≈ 2.589998 km² (slightly different from the international square mile of 2.59 km²)


This unit is mostly used in land surveying and mapping within the US.


Square Perch


A square perch is a traditional unit of area, also known as a square rod or pole. It represents the area of a square with sides one perch (rod) long.



  • 1 perch (rod) = 16.5 feet



  • 1 square perch = 16.5 ft × 16.5 ft = 272.25 square feet ≈ 25.29 square meters



  • 160 square perches = 1 acre



Square perches were commonly used in land surveying and property descriptions, especially in the UK and older US records.
