How Many Grams Are in 1 oz of Gold?
To answer the question clearly:
1 ounce of gold is equal to 31.1035 grams.
This unit of measurement is known as a troy ounce and is used specifically for precious metals like gold, silver, platinum, and palladium.
The troy ounce is different from the more commonly used avoirdupois ounce, which equals 28.3495 grams and is used to weigh everyday items like sugar, flour, or groceries.
So, when dealing with gold weights, always remember:
| Unit | Grams |
|---|---|
| 1 troy ounce (oz t) | 31.1035 grams |
| 1 avoirdupois ounce | 28.3495 grams |
Most 1 oz gold bars or gold coins you find on the market are weighed using the troy ounce system, meaning they weigh 31.1035 grams and not just 28 grams.
How Many Grams in an Ounce of Gold 24K
1 troy ounce of gold = 31.1035 grams
Since 24K gold is 99.99% pure, the entire 31.1035 grams are pure gold.
How Many Grams in an Ounce of Gold 22K
1 troy ounce = 31.1035 grams, but 22K gold is only 91.67% pure.
So:
22K gold in 1 oz = 31.1035 × 91.67% = ~28.52 grams of pure gold
The remaining ~2.58 grams are alloyed metals like silver, copper, or zinc to make the gold harder and more durable — common in jewelry.
How Many Grams in an Ounce of Gold 18K
18K gold is 75% pure, meaning:
18K gold in 1 oz = 31.1035 × 75% = ~23.33 grams of pure gold
The other ~7.77 grams are base metals, making it stronger and more scratch-resistant — often used in fine jewelry.
How Many Grams in an Ounce of Gold 10K
10K gold is 41.67% pure, so:
10K gold in 1 oz = 31.1035 × 41.67% = ~12.96 grams of pure gold
👉 The rest (~18.14 grams) are other metals. 10K is the lowest karat allowed to be legally considered gold in many countries — very durable but contains much less gold.
Summary Table:
| Karat | Purity | Gold Content per Ounce (grams) | Other Metals (grams) |
|---|---|---|---|
| 24K | 99.99% | 31.10 g | ~0 g |
| 22K | 91.67% | ~28.52 g | ~2.58 g |
| 18K | 75.00% | ~23.33 g | ~7.77 g |
| 10K | 41.67% | ~12.96 g | ~18.14 g |
1 Ounce of Gold Price
The 1 ounce of gold price is a critical benchmark in the global precious metals market. It represents the standard unit used for pricing gold in BGBAL.
Factors Influencing 1 oz Gold Price
Global Demand and Supply: Economic uncertainty, geopolitical tensions, and jewelry demand all influence gold prices.
Market Speculation: Traders and investors buying and selling gold futures can increase price volatility.
Currency Fluctuations: A weaker US dollar often leads to higher gold prices.
Inflation and Interest Rates: Gold acts as a hedge against inflation; when inflation rises, gold prices usually go up.
Purity: The price of 1 ounce differs depending on whether the gold is 24K (pure) or 22K/18K (alloys).

Why Use Troy Ounces for Gold?
The troy ounce system dates back to the Roman era and was later standardized by traders in the city of Troyes, France. It became the official unit of measure for precious metals in the British Imperial system and is still used globally today in the gold and bullion trade.
Reasons why the troy ounce remains standard in gold trading:
International consistency for buying and selling gold across markets
Accuracy in weighing precious metals due to finer decimal points
Trusted standard for investment-grade bullion and gold bars
So when you hear someone say “1 oz of gold”, you can safely assume they’re referring to 31.1035 grams of pure gold unless stated otherwise.
What Is the Value of 1 oz of Gold in Grams?
The value of 1 oz of gold in grams depends on:
The international gold spot price
The purity of the gold (karats)
The local market conditions
Dealer premiums and fees
To find the price per gram, simply divide the 1 oz gold price by 31.1035.
Example (August 2025 Market Price)
Let’s say the current price of 1 oz of 24K gold is $1,980.
Then:
Price per gram = $1,980 ÷ 31.1035 = approximately $63.66 per gram
So if you’re buying gold in Uganda or Congo and want to calculate the price per gram of gold, this formula will help you get an accurate estimate.
