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.
In writing, the chain (US survey) is usually shortened to "ch". One chain (US survey) is 20.11684023 meters, and that ratio is what every figure on this page is built from.
