1 oz = 0.0283495231 kilograms
Answer:
Gold is weighed on the Troy ounce basis. A 1 kg mass of gold would be 32.15 oz. Troy.
If you weighed the same mass of gold on your kitchen scales using the Avoirdupois system the reading would be 35.27 oz. Avoirdupois
To convert grams to ounces, divide the gram weight by 28.35 (1 ounce = 28.35 grams). So, 227 grams of 18 karat gold is approximately 8 ounces.
What purity of gold is it? (ex: 14 karat? 18 karat?)
If your gold is 24 karat -- i.e., pure gold, three grams weighs 0.105821 ounces and today's spot gold price per ounce is US$1,520, you can do the math and figure out how much your gold is worth. If, however, your gold is a different karat purity, such as 9, 10, 14, or 18, 22 karat, you'll need to factor in how much gold you really have and price it accordingly.

24 karat gold is more valuable than 18 karat gold because it is purer, with a higher gold content (99.9% pure gold compared to 75% in 18 karat gold). However, 18 karat gold is more durable due to the alloy metals mixed with the gold.

There is no 18 Karat gold in an ounce of 24 Karat gold because 24 Karat gold is pure. 18 Karat gold is alloyed with another metal to make it wear longer.

It would take more than 31.1 grams of 18 Karat gold to equal the pure gold content of 1 oz. of 24 Karat gold.
