Surveyor's Chain to Feet Converter
Gunter's chains and links to feet and metres — the unit old revenue maps and legal descriptions still use.
Gunter's genius: 10 square chains make exactly one acre, marrying decimal math to imperial units. Old Indian revenue maps at 16″=1 mile are gridded in chains — this converts them.
Formula
Surveyor's Chain to Feet Converter is a free chain to feet for surveyors, civil engineers and property buyers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Surveyor's Chain to Feet Converter
