What is Miles?
Miles (mi) is a unit of length. The mile is a unit of length equal to exactly 1,609.344 meters. It is defined internationally based on the statute mile standard agreed upon by the United States and countries using Imperial units [bipm-si-brochure]. The mile is used primarily for measuring distances on land and in navigation. The mile traces back to Roman times, originally defined as 1,000 paces. The modern statute mile was standardized in 1593 by an English Act of Parliament and internationally fixed in 1959 to 1,609.344 meters to unify measurements [bipm-si-brochure]. Miles remain official units of length in the United States, United Kingdom, and some Caribbean countries. It is commonly used in road distances, aviation, and maritime navigation, despite the global trend toward metric units [nist-sp-811].
What is Chains?
Chains (ch) is a unit of length. A chain is a unit of length equal to 66 feet or exactly 20.1168 meters. It was historically used in land surveying and equals 100 links. The chain is defined as 66 feet to maintain consistency with imperial measurements and is standardized for surveying purposes [nist-si-guide]. The chain was introduced by Edmund Gunter in 1620 to simplify land measurement and surveying. Adopted widely in English-speaking countries, it facilitated mapping and land division before metric units became prevalent [nist-si-guide]. Chains are primarily used in surveying and real estate in the United States, Canada, and parts of Australia. Although largely replaced by metric units globally, chains remain a legal unit in some jurisdictions for land records [nist-si-guide].
