1oz to Grams Gold: The Direct Answer
1 troy ounce of gold equals 31.1034768 grams.
To convert any number of troy ounces to grams, multiply by 31.1034768. To convert any number of grams to troy ounces, divide by 31.1034768.
This works for any quantity: 1 oz equals 31.1034768 grams. 2 oz equals 62.2069536 grams. 5 oz equals 155.517384 grams. 10 oz equals 311.034768 grams. 32.15 oz equals approximately 1,000 grams (1 kilogram).
And from grams to ounces: 1 gram equals 0.032150747 troy ounces. 10 grams equals 0.32150747 troy ounces. 31.1 grams equals approximately 1 troy ounce. 100 grams equals 3.2150747 troy ounces. 1,000 grams equals approximately 32.1507 troy ounces.
Understanding the Oz in 1oz to Grams Gold
When gold traders write “1oz,” they mean 1 troy ounce, never the avoirdupois ounce. This matters because the two types of ounce weigh different amounts.
The troy ounce, used for gold and precious metals, equals 31.1034768 grams. The avoirdupois ounce, used for everyday goods, equals only 28.3495 grams.
The troy ounce is about 9.7% heavier. This might sound like a small difference, but it has meaningful financial consequences. At $2,300 per troy ounce, 1 troy ounce of gold is worth about $2,300. If someone mistakenly calculates using 28.35 grams instead of 31.10 grams, they effectively undervalue the gold by about $224 per ounce. On a 50-ounce order, that error exceeds $11,000.
This is why the gold industry insists on the term “troy ounce” and why the “1oz to grams gold” conversion must always use 31.1034768.

The 1oz to Grams Conversion in Uganda’s Gold Market
Uganda’s domestic gold market operates with a mix of metric and troy measurements, reflecting both the country’s use of the metric system for everyday goods and the international standards required for export.
At the mining and procurement level, small quantities of gold are often weighed in grams using digital scales. Local traders might discuss quantities in grams or even traditional measures. But when this gold enters the formal export pipeline, it must be documented in troy ounces to comply with international standards.
Minerals Base Agency manages this transition seamlessly. As Uganda’s leading gold and silver seller and exporter, we work with local suppliers using gram-based measurements and translate those into troy ounce documentation for our international buyers. This ensures that our buyers receive documentation they can directly compare to international market prices and use with their own banks, refineries, and customs authorities.
Why the 1oz to Grams Gold Conversion Has Stayed Unchanged for Centuries
