How this is calculated
1 troy ounce = 31.1034768 g. This is the unit the spot market itself quotes, so no conversion is applied. Gold trades per troy ounce, so every figure here starts from that quote and is converted with the factor shown next to the result.
This is the metal's spot value. Dealers buy below it and sell above it — the gap is their margin, typically a few percent.
