A troy ounce is not a regular ounce
The troy ounce used for precious metals equals 31.1035 grams, while the avoirdupois ounce used in general trade is 28.3495 grams. The difference is nearly 10%, so mixing them up when calculating a piece's value is an expensive mistake.
When you see "gold at $2,700" in the news, it always refers to a troy ounce of pure gold. To convert to euros per gram, divide by 31.1035 and apply the exchange rate.
