However, when you are dealing with gold, you would most probably encounter the word 'troy ounce'. This measurement is the one that is being referred to in gold bars and gold businesses.

Historians believe that this term originated from the ancient Romans. As they developed and practiced a standard monetary system, they also created this measurement.

Bronze bars are the commonly used precious metals during that time. In a certain metallurgical process, it is broken down into 12 pieces called 'uncia', or ounce, which weighs 31 grams.

Small differences would later contribute to a larger discrepancy, especially if a buyer or investor will buy gold bars in bulk. Therefore, it is imperative to learn about this differences.
