@AlisonW @Iwillyeah Chains (which were actual steel link chains) were widely used in the UK for land survey hence an acre is area of one chain by one furlong (66 by 660 feet).
A furlong is 10 chains.
The length of cricket pitch is 1 chain.
As well as race courses distances on canals are traditionally measured and reported in miles and furlongs. Not doubt road distances were too at one time.
