How to calculate the gold price per gram?
Complete guide on converting troy ounces to grams and applying exchange rates.
At a glanceThe price of gold is quoted in USD per troy ounce (31.1035g) on international markets. To obtain the price per gram in CHF, three steps are necessary: divide the London Fixing rate by 31.1035, then multiply by the current USD/CHF exchange rate.
Formula: Price/g (CHF) = (LBMA Price in USD ÷ 31.1035) × USD/CHF Rate
Concrete Example: If gold is quoted at 2,900 USD/ounce and USD/CHF is at 0.90, then: (2,900 ÷ 31.1035) × 0.90 = CHF 83.92/g.
For 18-karat gold (750‰), you then multiply by 0.750: CHF 63.00/g. This is the pure theoretical spot price, before any margins or melting fees.
