Kiloparsec
A kiloparsec (kpc) is a unit of distance used in astronomy equal to 1,000 parsecs, or about 3,260 light-years. It is commonly used to measure distances within and between galaxies. For example, the Milky Way galaxy is about 30 kiloparsecs in diameter. Kiloparsecs help astronomers describe large-scale structures in space more conveniently than using light-years alone. The symbol for kiloparsec is "kpc". It’s an important unit for understanding the size and scale of galaxies and their components.
Chain
A chain is a unit of length traditionally used in land surveying. The most common version is the Gunter’s chain, which equals 66 feet or 22 yards, approximately 20.1168 meters.
The chain was introduced by English clergyman Edmund Gunter in the 17th century to simplify land measurement. One chain consists of 100 links, each 0.66 feet long. It became a standard unit in British and American land surveying and was instrumental in defining land areas, especially in the U.S. Public Land Survey System.
Key Conversions:
1 chain = 66 feet
1 chain = 22 yards
1 chain ≈ 20.1168 meters
10 chains = 1 furlong
80 chains = 1 mile
Though now largely replaced by metric units and modern surveying tools, the chain still appears in older land deeds, maps, and rural property descriptions.
