Dollar gold to silver ratio be exactly 15.5. Then a pennyweight of gold, that is 24 grains of gold, is nearly equal in value to a dollar of silver (1 dwt of gold = $1.002 of silver). Second, a dollar of gold is nearly equal in value to a pound of silver ($1 of gold = 5754 3/8 grains of silver = 0.999 Lb of silver). Third, the number of grains in a dollar (371.25) roughly equals the number of grams in a troy pound (373.24). The actual process of defining the US silver dollar had nothing to do with any
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
