## Calculation

1 troy ounce = 31.1034768 grams.
Price per gram = USD gold price per troy ounce / 31.1034768.
Converted price = USD gold price per troy ounce × units of BTC per USD × weight in grams / 31.1034768.
Jewelry metal value = weight in grams × converted price per gram × karats / 24.
Asset conversion rates are units of the asset per USD. Metals use troy ounces, copper uses pounds, oil uses barrels, natural gas uses MMBtu, and stocks and ETFs use shares. Energy quotes are front-month futures references.
Inverse view = 1 / converted price, expressed in the selected gold weight per one asset unit. Add inverse=1 to the JSON price endpoint to request this value.

## Interpretation

Reference prices are not an offer to buy or sell. Dealer premiums, local taxes, fabrication costs, purity, and fees can change the physical price. Currency reference rates may be older than the gold quote. Crypto timestamps are retrieval times when the upstream does not supply a market timestamp. Charts match historical prices for both sides by UTC date, or within 15 minutes intraday. Daily FX references carry over holidays for up to 4 days. Missing history is never replaced with current rates; coverage starts where both series have data.
