Standardized linear units of measure made up of twelve inches, 1/3 of a yard; equal to 0.3048 meters. It was a unit of length in both the imperial and US customary systems of measurement; since 1959, both units have been defined as the same by international agreement. Originally the unit was based on the length of a man's foot, varying in exact length at different periods and in different countries.
