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 spot-derived value, not the shop counter price in Japan. Local retail rates are set by the jewellers' association and usually sit above this figure once making charges and duty are added.
