Feathers, Gold, and also Word Play, or is it?

The old riddle goes: what weighs an ext a pound of feather or a pound of gold? some say gold due to the fact that it is heavier. Rather say they are both a lb so they sweet the same. Both are wrong. How have the right to this be? Tradition. Yellow is not weighed in the plain weights. Yellow is sweet in the troy measurement system. One ounce of yellow is no the exact same as the ordinary ounce (really dubbed avoirdupois ounce).

The best method to recognize this is to convert them both come a uniform system. A gram or gramme is a conventional metric unit that mass. One avoirdupois ounce converts to 28.34 grams approximately. The trojan ounce is 31.1 approximately. Friend say, “Aha! Gold sweet more, therefore a pound of gold weighs an ext than a pound of feathers.” regrettably there is one more piece that the puzzle. We all understand 16 ounces equal a pound. True in the avoirdupois system, but not in the troy. In the Troy system only 12 ounces equal a pound. Therefore a pound of feathers weighs 453.59 grams approximately and also a lb of yellow weighs 373.24 approximately. For this reason a lb of feathers weighs an ext then a lb of gold.

Some speak gold due to the fact that it is heavier. Others say they room both a pound so they weigh the same. Both space wrong.

There is an ext trivia about gold weights. The troy mechanism historically was provided for measuring the weight of drugs, priceless metals and gemstones. The name comes from the French city of Troyes. The noble steels (gold, silver and also platinum) all use the troy system. A troy ounce is 20 pennyweights. The pennyweight to be the weight of a silver penny in medieval England. Once pennies were presented in England in the 8 hours century, their initial weight is thought to have actually been 24 grains. This was progressively reduced, in at the very least thirteen stages until it reached 7.27 grains by 1816. 24 seed = 1 pennyweight and 20 pennyweights = 1 oz troy.

Even an ext trivia if you’d choose to check out on. “Grain is an old unit which was originally based upon the weight of a grain of wheat. The serial is the smallest unit of load in the avoirdupois, troy, and also apothecaries systems. Surprisingly it is similar in all three systems.” 4 grains = 1 carat; 24 grains =1 pennyweight; 480 grains = 1 trojan ounce; 15.432 grains = 1 gram.

“Although we have actually stated above that the grain sweet the very same in all three of the above systems, there were at least two various grains. The troy device used the supposed weight the the barley grain, conversely, the wheat serial was likewise used as a conventional of weight. Over there were three barley grains to 4 wheat grains.”

That is sufficient trivia for now. If you want to upgrade the old riddle, you could say: what weighs more, a kilo of feathers or a kilo of gold?
