The Imperial system is used, but the Cental replaces the long Cwt. and its stone divisions.
In the old French districts of Quebec certain old French measures are lawful: the Paris foot, the perch, usually of 20 feet, the Arpent of 100 perches.
The Minot, of 3 boisseaux = 1·073 bushel, is still used.
This island, formerly a French colony, retained the old French measures and weights: the Paris foot, the Toise, the Mille of 1000 toises = 1·21 mile, the Perch, usually of 18 feet, the Arpent of 100 perches, the French livre, the corn-setier, the wine-setier or Velte = 1·639 gallon.
The Metric system was substituted in 1876, notwithstanding that ‘the feeling of a great portion of the community was so strongly against it that in 1882 it was thought to be not improbable that the British Imperial weights and measures might be reverted to’ (‘Merchants’ Handbook,’ by W. A. Browne, 1899). It is added that this antagonistic feeling gradually died out, but evidence on this point would be desirable.

In all times money has been the weight of a certain amount of copper, silver or gold, in the form of coins the fineness of which is guaranteed by the stamp of the State. The weight of coins used in payments may change in course of time, but the nominal unit of weights often continues, the pound, or livre, or marc, &c. Thus, the original Roman unit, the As, or mint-pound of copper or bronze, reduced gradually to 1/24 of its primitive weight, persisted as a money of account long after it had been replaced in the currency by the silver Denarius. This was originally coined at a time when it represented the value of 10 As; hence its name deni-aris, ten of copper.
The French livre, or livre d’estelins, reduced gradually to a coin about 1/74 of a 12-oz. livre, retains its name as a synonym of the franc.
The English pound of silver, once a Tower pound = 5400 grains, reduced long ago to 1745 grains, in 20 shillings, persists as a money of account, though the silver is superseded in payments over 40 shillings by a gold coin weighing 123-1/4 grains. Prices over 40_s._ are still often stated in shillings.
The Roman denarius originally weighed 60 grains, afterwards reduced to 52-1/2 grains. A golden denarius was also coined, which afterwards became the Arabic dinar.
