How heavy is a Troy Ounce?

What is 'Scrap' gold value?

Scrap value is the value of the raw metal content. When selling to a dealer, expect to receive 80-95% of the calculated market value to account for refining and profit margins.

No. For an accurate gold calculation, you should subtract the weight of any gemstones or diamonds. This calculator assumes the total weight is metal only.
