Gold Price per Troy Ounce

The troy ounce is the unit international bullion markets, exchanges and this platform's own underlying provider quote Gold in natively — for a reader working in the currency this platform's metal reference is already denominated in (or comparing against international spot conventions), this is the most direct figure this platform can show, with the least conversion between the source and the number on screen.

How this unit is defined

A troy ounce equals exactly 31.1034768 grams — distinct from the everyday avoirdupois ounce (28.3495 g) used for most other goods. Precious metals have used the troy system for centuries specifically to avoid that ambiguity; this platform's weight-conversion engine uses the troy definition throughout.

How this figure is calculated

A verified Gold 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 timestamp for both the metal price and, where used, the FX rate.

Questions

Is this the international spot price?
It is this platform's own calculated reference, sourced from its metals data provider and, where you have selected a non-USD currency, converted using a verified FX rate. It is not a live trading feed and carries no bid/ask spread — see the provenance line under the figure for the exact source and timestamp.
Why is USD the most direct currency for this page?
This platform's Gold reference is itself quoted in USD, so a USD troy-ounce figure needs no currency conversion at all — it is the platform's Reference classification, not a Calculated Reference. Any other currency adds one verified FX conversion step, shown in the provenance line.
How does this relate to the per-gram or per-tola price?
All three are the same underlying Gold reference, expressed in a different weight unit via this platform's one shared conversion engine — see Gold Price per Gram and Gold Price per Tola for those views.
