Good to know
These are not retail buy/sell quotes or KRX execution prices. Tax, dealer margins, and workmanship are excluded. 18K and 14K values reflect theoretical gold content only.
How many grams are in one don?
One don is 3.75 grams. Gold uses troy ounces, not ordinary ounces: 1 troy ounce equals 31.1034768 grams. The estimated KRW value of one don is the USD price per ounce ÷ 31.1034768 × 3.75 × the USD/KRW rate.
What do 24K, 18K, and 14K mean?
This calculator treats 24K as pure gold and applies gold-content fractions of 18/24 for 18K and 14/24 for 14K. Actual purchase offers can differ because of appraisal, refining costs, and the buyer’s pricing policy.
