Tons cwt. qes. and lbs. are brought to the form of £ s. d. by making the pounds the fraction of a quarter, and multiplying this by 3 for pence; the tons and cwts, being taken as pounds and shillings. For as 20 shillings make a pound, and 20ct. make a ton at 20s. P. ton, 1 cwt, costs 1 shilling, and a quarter of an cwt, 3 pence, whence the rule is manifest.

Pounds, oz. dwts. and grains troy, by making the grains the fraction of a penny-weight, and multiplying the oz. by 200. adding thereto the penny-weights and fraction thereof counted as pence; for there are 240 penny weights in a pound troy and 240 pence in a pound, and at that price loz cost ls. 8d. or l; shillings.
