How the gold price in Thailand is calculated
We take the live spot price of 4,121.20 USD per troy ounce, divide it by 31.1035 to get 132.50 USD per gram of pure gold, and multiply by today’s exchange rate of 33.6384 THB per dollar. That gives 4,457.08 THB per gram for 24K. Lower karats are priced by their gold content.
Thailand uses the baht weight: one baht of 96.5% gold bar equals 15.244 g. The Gold Traders Association publishes official buy and sell prices several times a day.
Before you sell, weigh your pieces on a jeweler’s scale, check the hallmark and compare at least two quotes. Read our guide to selling gold.
