How the gram price is derived
Although Danish shops quote per gram, the global market quotes gold in US dollars per troy ounce. One troy ounce equals exactly 31.1034768 grams, so the pure gold (24K) gram price is the ounce price divided by 31.1034768, converted to DKK at the live exchange rate. Lower purities are then a simple multiplication: 22K/916 is the 24K gram price × 0.9167, and 18K is × 0.75.
Danish dealers quote in kroner per gram and ounce, converted from the USD spot price at the USD/DKK rate — which is stabilised by the krone's peg to the euro through ERM II. As an EU member, Denmark applies the EU VAT exemption for investment gold.
