Troy Ounce to Ounce

Relation between ounce and troy ounce

When you bid for the prices of precious metals in auctions on online sites, the items are mentioned according to their weight in troy ounce. But in many of these auction sites, they may also mention the word ‘ounce’ instead of ounce, and if you consider that both are the same, then you will get a shortage of nearly 9% in the value of the precious metal. Hence, it is important to know the relation between troy ounce to ounce and know the difference. The spot price of precious metals is usually mentioned in troy ounces.

Precaution at online auctions

If you see any item mentioned in ounces on any of these sale or auction websites, then you need to verify whether it is troy ounce or the more common avoirdupois ounce. If the seller has mentioned ounces, and if you consider it as troy ounce, then you may lose in the bargain, as you will be paying for a troy ounce and getting only an ounce value. The avoirdupois ounce is lighter than the troy ounce. The perceived value is thus boosted or increased by about 9%, as this is the amount by which a troy ounce is greater than the common ounce. However, if you realize that the weight mentioned is the avoirdupois ounce, then you should immediately multiply it by .91, which will give you the weight in troy ounce. This is the correct way to convert ounce to troy ounce.

Pounds into troy ounce

Many of these auction sites also mention the term ‘postal ounce’, which is also quite different from the troy ounce, and should also be multiplied by .91 to get the troy ounce weight. The price mentioned is usually in dollars and is always for a troy ounce. Even in the case of pounds, there is a difference, as there are 12 troy ounces in a troy pound and 16 avoirdupois ounces in the common pound. In order to convert troy ounce to ounce, the troy ounce weight should be multiplied by 1.09714 in order to get the value in ounce. A troy is nearly 1.1 times heavier than the avoirdupois ounce.

Apart from converting from troy ounce to ounce, it is also noticed in many online sales and auctions, that when the price is listed in pounds, they don’t mean troy pounds, but rather the avoirdupois pounds. You may have to convert this avoirdupois or common pound into troy ounces. One avoirdupois pound is equivalent of 14.5833 troy ounces. Hence the value of the avoirdupois pound weight must be multiplied with this number in order to obtain the weight in troy ounce.
