What is a rod (US survey)?
The rod (US survey) is a US survey unit. One rod (US survey) equals 5.029210058 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 rod (US survey) is usually shortened to "rd". One rod (US survey) is 5.029210058 meters, and that ratio is what every figure on this page is built from.
