Twenty-four karat is the "pure" lane — bars, rounds, some jewelry, and scrap stamped 999. Sellers still mess it up by weighing in avoirdupois ounces or treating plated yellow metal as bullion.
One wrong unit on a "one ounce" piece and your phone math is theater. One wrong purity on fashion "24K look" plate and you're inventing metal.
This calculator runs near-pure math (≈ 99.9% / 999) against the weight you actually put on the scale.
Pure isn't the same as "whatever looks yellow"
Solid 24K jewelry exists, but it's soft. A lot of consumer "pure gold" talk is marketing for plating. If there's no 999, 24K, or assay card, don't gift it purity in the calculator.
Investment bars and rounds usually publish fine gold content. Prefer stated fine troy ounces over guessing from total weight when the paperwork is clear.
Scrap "24K" filings and dental-adjacent junk need honesty: if you didn't assay it, you're running a scenario.
How to run a clean 24K estimate
Weigh on a scale you trust. Use grams or troy ounces — not kitchen ounces.
Set purity near 0.999 (or enter the exact fineness on the bar). Multiply by spot on the same unit basis.
Compare the melt-style number to melt-ish offers. Minted bullion with tight spreads may trade near spot; odd scrap will not.
Unit refresher if the scale and the ticket disagree: pennyweight vs grams vs troy ounce.
24K reference sheet
| Measure | Figure |
|---|---|
| Karat | 24K |
| Typical fineness | 999 (sometimes 999.9) |
| Purity used here | ≈ 99.9% |
| 1 troy oz fine | 31.1035 g |
| Pure gold in 10 g of 999 | ≈ 9.99 g |
Value ≈ weight × ≈0.999 × gold price (matched units). For stated "1.00 oz fine" bars, weight in fine ounces × spot is enough.
EXAMPLE — 10 g of 999 scrap
EXAMPLE spot: $4,000 / troy oz (illustrative).
Pure gram ≈ 4000 ÷ 31.1035 ≈ $128.60.
Lot: 10.00 g confirmed 999 scrap.
Fine ≈ 10 × 0.999 = 9.99 g
Melt-style ≈ 9.99 × 128.60 ≈ $1,285.
Same 10 g as 22K (≈0.917) prints ≈ $1,179. Calling scrap "basically pure" without a mark leaves about $100 of fiction on a tiny lot.
Bullion premiums vs melt floor
A sealed, liquid bar can clear near spot with a small dealer spread. A scratched, odd-weight pour may sit under. Jewelry stamped 24K still faces scrap-style discounts if it's going to a melt buyer.
Don't use this page to invent collector premiums. It prices metal. Premiums are a separate phone call.

Frequently Asked Questions
Is 24K exactly 100% gold?
Commercial 999 is ≈ 99.9%. Some products mark 999.9. Neither is laboratory absolute zero impurities — close enough for trade math.
Can I price a 1 oz bar here?
Yes. Enter 1 troy oz fine (or total weight × fineness). Multiply by spot for melt-style value.
Why doesn't my cash match spot?
Spreads, assay on odd lots, and buyer margin. Retail buy-back on branded bars differs from scrap tickets on broken jewelry.
Is plated "24K" the same?
No. Plating thickness is tiny. Don't run plate through a 24K purity field.
Grams or troy ounces?
Both. Jewelry scales lean grams; bullion talk leans troy ounces. Never mix avoirdupois ounces into troy math.
What about 24K coins?
Use fine gold content × spot for melt. Check premiums and authenticity before you sell or scrap.

Near-pure estimates assume stated fineness. Fake stamps and plated goods exist. Settlement follows assay and buyer terms.
