If you've weighed silver on a kitchen or postal scale and got a reading in standard ounces, this is the figure you need - the silver price per avoirdupois ounce is 28.35 grams, roughly 10% less than the troy ounce used as the global silver pricing standard. The live rate in USD below updates in real time, bridging the gap between your scale reading and the actual market value of your silver.
When most people say "ounce," they mean avoirdupois. It is the ounce on every kitchen scale, every postal scale, every bathroom scale sold in the US and UK. It is the ounce that tells you how much a block of cheese weighs, how heavy a parcel is, how much a baby gained since last week. It is, by any measure, the ordinary ounce - 28.3495 grams, used for virtually everything that gets weighed in everyday life.
Silver does not use it.
Every silver price you see on a financial feed, a dealer's website, or a futures exchange is quoted in troy ounces - 31.1035 grams, a unit specific to precious metals that most people only encounter when they start looking up what their silver is actually worth. The gap between the two ounces is about 2.75 grams, or roughly 10%. That is not a rounding error; over any meaningful quantity of silver, it is real money that disappears if you use the wrong unit.
GoldPrice.Live displays the live silver price per avoirdupois ounce for exactly this reason - so that if you have weighed silver on a standard scale and got a reading in regular ounces, you can value it directly without needing to convert to troy ounces first. The rate updates continuously from the live XAG spot market.
The troy-versus-avoirdupois problem catches people in a few specific situations, and it is worth naming them clearly.
The most common is the kitchen or postal scale scenario. Someone inherits a bag of old silver coins, a set of flatware, or a handful of silver rounds. They put them on whatever scale they have at home - which reads in standard ounces - look up the silver spot price, multiply, and get a number that is about 10% higher than what their silver is actually worth. The confusion is almost always in that direction: people think they have more value than they do because they multiplied a troy ounce price by an avoirdupois weight.
The second situation is auction listings. Search for silver on any major online auction platform and you will regularly encounter listings that describe weight in standard ounces rather than troy ounces. A listing for "16 oz of silver coins" sounds like it should be worth roughly the spot price of 16 troy ounces - but if the seller weighed on a standard scale, those 16 avoirdupois ounces are actually only about 14.6 troy ounces of silver. Again, the buyer who does not know this overpays; the seller who does not know this underprices.
The third situation is industrial and commercial purchasing, where companies buying silver for manufacturing - electronics, solar cells, medical devices - may source metal in metric quantities but need to reconcile their weights against spot prices quoted per troy ounce. The conversion matters at scale.
For all three situations, the per avoirdupois ounce rate on this page removes the need to do that conversion manually. Weigh in standard ounces, read the value directly.
The avoirdupois ounce silver price is derived from the international silver spot price in USD per troy ounce by multiplying by 0.91146 - the ratio of one avoirdupois ounce (28.3495g) to one troy ounce (31.1035g). Because the avoirdupois ounce is lighter than a troy ounce, the per avoirdupois ounce price is always lower than the per troy ounce price at any given moment. If silver is trading at $32.00 per troy ounce, the avoirdupois rate is $32.00 × 0.91146 = approximately $29.17 per standard ounce.
That 91 cents per ounce difference at $32 spot might look manageable on a single ounce. Across 100 standard ounces of silver - not an unusual amount for someone clearing out a full flatware service or a coin collection - the total error is about $91. Across 1,000 ounces, it is nearly $1,000. The conversion is simple, but skipping it is an expensive habit.
If you prefer to work in grams rather than either type of ounce, the silver price per gram page gives you the live rate in the most universal unit - grams are grams regardless of which ounce system a scale uses.
Here is something that trips up even buyers who know about the troy-versus-avoirdupois ounce distinction: while precious metals use the troy ounce, they do not use the troy pound.
The troy system has its own pound - 12 troy ounces, equal to 373.24 grams. The avoirdupois pound contains 16 avoirdupois ounces, equal to 453.59 grams. So the troy pound is actually lighter than a standard pound, not heavier.
In practice, no modern bullion market quotes silver by the pound in either system. Silver is sold in troy ounces, grams, or kilograms. But this matters enormously on secondary markets and auction platforms where uninformed sellers occasionally list silver "by the pound," and it is not always clear which pound they mean. A seller who weighed silver on a kitchen scale and listed "1 lb of silver" is describing 16 avoirdupois ounces - about 453 grams, or 14.58 troy ounces. If a buyer interprets that as 12 troy ounces and prices accordingly, someone is making a significant error.
The silver calculator handles all of these unit conversions at the live spot rate, which is the cleanest way to sidestep the arithmetic entirely when you are valuing a mixed lot of silver in different units.
Silver's industrial consumption - across solar panels, electronics, medical equipment, and water treatment - runs into tens of thousands of tonnes annually. Industrial procurement teams purchasing silver for manufacturing operations generally work in kilograms and metric tonnes, not troy ounces. But the spot price reference they price against is always quoted in troy ounces per the COMEX and OTC markets.
Converting accurately between these systems is not optional in an industrial context; a 10% error on a multi-tonne silver purchase is a material financial loss. This is why procurement contracts for industrial silver are written with explicit unit specifications, and why any ambiguity between avoirdupois and troy systems is treated as a contract drafting failure rather than a minor confusion.
For ongoing market price context and trend monitoring, the silver price charts display historical XAG performance across intraday through multi-year timeframes - useful whether you are timing an industrial purchase or tracking the spot rate that underlies any avoirdupois conversion.
