Gold Price Per Gram
Use the main calculator to convert the live troy ounce gold price into a clear gold price per gram estimate.
Gold price per gram formula
Gold price per gram equals the troy ounce price divided by 31.1035. The calculator then adjusts that value by karat purity for jewelry and scrap gold.
Why troy ounces matter
Gold markets quote spot price per troy ounce, while jewelry is often weighed in grams. A troy ounce is 31.1035 grams, not a regular ounce.
How karat changes gram value
A 24K gram is close to pure gold. A 14K gram contains about 58.3% fine gold, and a 10K gram contains about 41.7% fine gold.
When to use manual price
Use manual price when you have a local quote, buyer rate, broker price, or trusted market price that differs from the live feed.
How to compare buyer quotes
Select currency, choose grams, pick karat purity, and compare the spot value with 90%, 80%, or 70% dealer payout options.
Common question
Gold price per gram is not the same for every karat. Lower karats are worth less per gram because they contain less fine gold.
