Is a troy ounce the same as a normal ounce?

No, and the difference is material. A troy ounce is 31.1034768 g; the everyday avoirdupois ounce is 28.349523125 g. A troy ounce is roughly 10% heavier. Every precious-metal figure on this platform uses the troy ounce.

Why is this called a Reference rather than a Calculated Reference in USD?

Because in USD no conversion is applied at all — the troy ounce is already this platform's own canonical observation unit for silver, so the figure is the verified reference itself. Select another currency and it becomes a calculated reference, because one verified FX rate is then applied.

Does a 1 oz silver coin contain exactly one troy ounce?

A 1 oz bullion coin normally contains one troy ounce of fine silver, but its total weight can be higher if it is alloyed. This page prices fine metal content, not gross coin weight, and it applies no collectible or premium value — what a dealer charges over spot is theirs, not a market fact.

Silver Price per Troy Ounce

The troy ounce is silver's native quoting unit: when a market report says silver moved today, the number it quotes is per troy ounce in US dollars. That makes this page the one silver figure that needs no weight conversion at all in its base currency — what you see is the platform's verified reference observation itself, not a derived number. It is also the unit that 1 oz rounds, the most widely held retail silver coin format, are denominated in.

How this unit is defined

A troy ounce is exactly 31.1034768 grams — a different and heavier unit than the 28.349523125 g avoirdupois ounce used for groceries. Precious metals are always quoted in troy ounces, and confusing the two overstates a holding's weight by about 10%. This page never uses the avoirdupois ounce.

How this figure is calculated

A verified Silver reference price is read from this platform's metals data provider, converted (via one verified FX rate, only when your selected currency is not USD) and converted to this page's unit using an exact conversion factor — never rounded before the arithmetic. The provenance line under the figure states the exact source and observation time for both the metal price and, where one was used, the FX rate. When no verified reference is available the figure is withheld and the card says so — it is never replaced by a zero or a last-known value presented as current.

Fineness, not karat

Silver is described by fineness rather than karat: fine silver is 999, sterling is 925, and coin silver is commonly 900. This page prices fine silver, so a sterling item is worth 92.5% of the figure shown for the same weight, before any dealer deduction. To apply a fineness and a deduction explicitly, use the Silver Value calculator or the Scrap Gold / Silver calculator.
