Put a kilogram quote on the right scale
One kilogram is 1,000 grams; its ounce equivalent is 1,000 / 31.1034768. Apply the weight conversion and then product purity. At 995 fineness, a one-kilogram item contains 995 grams of fine metal. Match currency, timestamps and purity when comparing per-kilo and per-gram prices. Several smaller packaged products can cost more than one larger product with the same contained metal.
A worked valuation
The following figures are a worked example, not current prices. Illustrative USD/troy-ounce reference: 3,100. 1 kilograms × 0.995 = 995 grams of fine gold. Illustrative metal value: 99,168.9778 USD.
This value is neither a dealer’s ask nor your net resale proceeds. Enter actual bid and ask quotes in the same unit and add total fees separately. Quotes taken at different times can also differ from a calculated reference. When changing currency in the calculator, remember that FX is a daily reference.
Separate the product premium
Fabrication, minting, branding and packaging can add to a product’s price. Paying a premium does not establish that it will be recovered on resale. Compare fine content and total transaction cost rather than gross grams alone. Use the dealer ask when purchasing and the dealer bid when reselling.
