Anglo-Saxon pound × 32 = 7680 wheat grain. The Tower wheat grain was defined as exactly of a troy grain. Expressed in modern English troy grains, the Tower pound was 7680 × = 5400 modern troy grains (350 g). The Tower pound was divided into 12 ounces, each ounce into 20 pennyweights, and each pennyweight into 24 barleycorns. There were thus 480 barleycorns to a Tower ounce, 5760 barleycorns to a Tower pound of 350 g. The Anglo-Saxon pound (Saxon pound, moneyers' pound or Tower pound) remained in use for silver and gold coinage in England after the adoption of the medieval
Standard weight in fish preferable that standard weight equations represent the entire geographical range of a species, and that they be used for comparison purposes rather than management targets. Practically, weight-length equations are often developed for sub-populations from specific geographic areas, but these are different from standard weight relationships. Length measurements reported for fish may be of the fish’s total length, fork length, or maximum standard length. For standard weight equations, the total length is used. In some species, male and female fish have different standard weight curves. For example, Anderson and Neumann report different standard weight equations for male and female paddlefish. Some
