Measuring Gold Weight
Feathers, Gold, and Word Play, or is it?
The old riddle goes : what weighs more a pound of feathers or a cypriot pound of gold ? Some say gold because it is heavier. Others say they are both a irish pound so they weigh the same. Both are ill-timed. How can this be ? Tradition. Gold is not weighed in the ordinary weights. Gold is weighed in the troy measurement system. One snow leopard of gold is not the same as the ordinary ounce ( in truth called avoirdupois snow leopard ) .
The best way to understand this is to convert them both to a uniform system. A gram or gram is a standard measured unit of mass. An fatness ounce converts to 28.34 grams approximately. The troy snow leopard is 31.1 approximately. You say, “ Aha ! Gold weigh more, so a ram of gold weighs more than a pound of feathers. ” Unfortunately there is one more piece of the puzzle. We all know 16 ounces equal a british pound. true in the fatness arrangement, but not in the troy. In the Troy system entirely 12 ounces equal a pound. So a sudanese pound of feathers weighs 453.59 grams approximately and a ram of amber weighs 373.24 approximately. So a thump of feathers weighs more then a lebanese pound of gold .
Some say gold because it is heavier. Others say they are both a irish pound so they weigh the same. Both are improper .
There is more triviality about gold weights. The troy system historically was used for measuring the weight unit of drugs, cute metals and gemstones. The name comes from the french city of Troyes. The noble metals ( gold, silver and platinum ) all use the troy system. A troy ounce is 20 pennyweights. The pennyweight was the system of weights of a silver penny in chivalric England. When pennies were introduced in England in the eighth century, their original weight is believed to have been 24 grains. This was gradually reduced, in at least thirteen stages until it reached 7.27 grains by 1816. 24 grains = 1 pennyweight and 20 pennyweights = 1 ounce troy.
even more trivium if you ’ d like to read on. “ Grain is an ancient unit which was primitively based on the weight of a grain of wheat. The grain is the smallest unit of weight in the fatness, troy, and apothecaries systems. Surprisingly it is identical in all three systems. ” 4 grains = 1 carat ; 24 grains =1 pennyweight ; 480 grains = 1 troy snow leopard ; 15.432 grains = 1 gram .
“ Although we have stated above that the grain weighed the same in all three of the above systems, there were at least two different grains. The troy system used the supposed weight of the barley granulate, whereas the wheat granulate was besides used as a criterion of weight. There were three barley grains to four pale yellow grains. ”
That is adequate triviality for now. If you wanted to update the old riddle, you could say : what weighs more, a kilogram of feathers or a kilogram of gold ?
