I bought a bullion round yesterday marked: One troy gram. Is a troy gram heavier or lighter than a regular gram? Siri was absolutely helpless.

I'm no expert, but I don't think there is a difference - grams are grams. Grams to troy ounces, for example, would be a more typical conversion, or grams to troy "grains".

It must be a troy grain, or simply one grain. There isn't a troy gram as far as I know.

Siri was absolutely helpless. well normal ounce is 28 grams - TROY ounce is 31.1 regular grams - so a troy gram should be a bit heavier than a regular gram weight. precious metals are weighed in TROY ounces (31.1 grams) - everything else is weighed in regular ounces (28 grams).

I didn't think the gram was different just how many of them in an ounce. The ounce should be described as troy, not the gram?

Since grams are a metric measure, I would have to think that there is no such thing as a "troy gram." According to Wikipedia, the Troy Weight system includes: Troy pound, Troy ounce, Pennywieght, Troy grain and Mint Weights. Quote:
The only troy weight in widespread use today is the British Imperial troy ounce and its American counterpart. Both are currently based on a grain of 0.06479891 gram (exact, by definition), with 480 grains to a troy ounce (compared with #8202;437 1#8260;2 grains for an ounce avoirdupois). https://en.wikipedia.org/wiki/Troy_weightAnd, a grain is a grain is a grain: Quote:
The grain was the legal foundation of traditional English weight systems, and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries' systems of mass. https://en.wikipedia.org/wiki/Grain_(unit) |

A gram is a gram. It's all about how many of them are needed to equal an ounce. There are two measuring systems, avoirdupois and troy. Avoirdupois is used to weigh everything from flour to cars to people. The troy system is used for precious metals and gem stones.
The avoirdupois system has 16 ounces to the pound while the troy system has 12. An ounce in the troy system, however, is heavier than one in the avoirdupois system. A troy ounce is equal to 31.0135 grams while an avoirdupois ounce is equal to just 28.3494 grams.
From the size of the silver round (it appears to be slightly smaller than a dime), I imagine it is very thin. One troy gram is just 1/31st of a troy ounce -- not much metal to work with!

It is very thin. Well, it does have 54 cents of silver in it, so I make 4 cents.  |

The ounce should be described as troy, not the gram? That makes no sense!! If 31.1 grams = a TROY once then why would 28 grams (like you imply) also = a troy ounce? Time for a mathematician to prove this!! |

So the Troy once is heavier to the ounce than a pound? So it is better to buy 16 ONE Troy ounce silver bars that a ONE pound Troy silverbar? I'm so confused!! |

Mark, if you had clicked on the Wikipedia links I posted, maybe you wouldn't be so confused.  Here's the pertinent info from that page: Quote:
Troy pound
The troy pound is 5 760 grains (#8776; 373.24 g, 12 oz t), while an avoirdupois pound is approximately 21.53% heavier at 7 000 grains (#8776; 453.59 g).
Troy ounce (oz t)
One troy ounce (oz t) is equal to 31.103 476 8 grams. Also equal to 1.097 142 86 avoirdupois ounces, exactly #8202;192#8260;175, or about 10% larger.
Pennyweight (dwt)
The pennyweight symbol is dwt. There are 24 grains in 1 dwt, and 20 dwt in one troy ounce. Because there were 12 troy ounces in the old troy pound, there would have been 240 pennyweights to the pound—the basis of the fact that the old British pound sterling of currency contained 240 pence. (However, prior to 1526, English pound sterling was based on the tower pound, which is #8202;15#8260;16 of a troy pound.) The d in dwt stands for denarius, the ancient Roman coin, referred to in the New Testament, that equates loosely to a penny. The symbol d for penny can be recognized in the notation for British pre-decimal pennies, in which pounds, shillings, and pence were indicated using the symbols £, s, and d, respectively. For example, £6 11s 8d indicated six pounds, eleven shillings, and eight pence.
Mint weights, also known as moneyers' weights were legalised by Act of Parliament dated 17 July 1649 entitled An Act touching the monies and coins of England. A grain is 20 mites, a mite is 24 droits, a droit is 20 perits, a perit is 24 blanks.[12] |

So it is better to buy 16 ONE Troy ounce silver bars that a ONE pound Troy silverbar? Better than what? If you buy 16 one troy ounce silver bars, then you will have 1 troy pound of silver PLUS 4 more troy ounces. You will pay 16 times the spot price of a troy ounce of silver to get your 16 1oz bars. You will pay about 12 times the spot price of a troy ounce of silver to get 1 troy pound bar or round. An ounce and a troy ounce aren't the same thing, except for the fact that they have the word "ounce" in common. A pound and a troy pound aren't the same thing, except for the fact that they have the word "pound" in common. You do NOT commonly buy silver in ounces. Instead, you buy it in troy ounces, even if they only call it "1 ounce". Still confused? |
