What is a chain (US survey)?
The chain (US survey) is a US survey unit. One chain (US survey) equals 20.11684023 meters, so every conversion on this page starts from that single number. Survey units come from a slightly older definition of the foot that the United States kept for land measurement, so they are a tiny fraction larger than the modern versions.
The difference is far too small to notice in a room, but across miles of property boundary it matters, which is why surveyors and deed records keep the two apart.
