A historical measurement of distance and length of land, traditionally equal to 40 rods.
A furlong is a traditional English measurement of distance, equal to 40 rods or 660 feet.
In agricultural records, furlong could also refer to a strip or section of land within an open-field system. The term was often used to describe the organisation and measurement of fields.
Because medieval measurements were based on custom, the exact meaning of land measurements could vary according to local practice.
