- the units of the British Imperial system, adopted by Parliament in 1824.The basic units of the system are the foot, the avoirdupois pound, and the Imperial pint. The Weights and Measures Acts of 1963 and 1985 have redefined the Imperial units in term of the SI units. The Imperial units remain in varying degrees of use in Britain, Canada, Australia, and other areas of British heritage despite the introduction of metric units there. Americans should note that the Imperial foot and pound are essentially the same as the units used in the U.S., but the Imperial pint is significantly larger than the U.S. liquid and dry pints.
