Chain (US Survey)
The US survey chain (symbol: ch) is a unit of length equal to 66 US survey feet, approximately 20.11684 metres, used extensively in the public land survey system of the United States. It differs slightly from the international chain due to the distinct definition of the US survey foot. The US survey chain formed the basis for the township-and-range system that divided most of the continental United States into parcels for settlement.
Meter
The metre (Commonwealth spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μετρούν, "measure") is the base unit of length in the International System of Units (SI). The SI unit symbol is m. The metre is defined as the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately 40000 km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. In 1983, the current definition was adopted.
