Pound (unit)

Definition and stakes

Various,  Chambers's Journal of Popular Literature… (1853)

“ As these weights of many irregular kinds had been largely used, various trades were much exercised by their abolition, and evasions have been frequent, and are not altogether unknown even now. By the Act of Parliament referred to, the imperial standard pound is the unit of weight from which all others are to be calculated: one-sixteenth part of a pound is an ounce ”

“ A 9subdivision of the talent would become the pound or common unit of weight in the retail market, and a subdivision of the pound would be fixed as the weight of silver which, impressed with signs guaranteeing its fineness, if not its actual weight, would be the currency of the merchants.
Then arose, by involution, another system of weights in which the pound was usually of 12 or 16 ounces, and the ounce was the weight of so many standard coins. Every modern pound was based on this system.

“ In the second class of cases the fraction of the unit quantity is a quantity of the same kind, but cannot be determined with absolute exactness. Weights come in this class. The ounce, for instance, is one-sixteenth of the pound, but it is impossible to find 16 objects such that their weights shall be exactly equal and that the sum of their weights shall be exactly equal to the weight of the standard pound. ”
