Platinum price per grain
One grain is 1/480 of a troy ounce, or about 0.0647989 gram. The table above shows the contained-platinum value per grain for every listed purity.
Pt950 and Pt900 Price per Gram
Each row values the contained platinum in one gram of that hallmark at the price above. A hallmark states the alloy as made; it is not an assay of a worn or repaired item.
| Hallmark | Fineness | Contained platinum value per gram | Where the mark appears |
|---|---|---|---|
| Pt999 | 0.999 fine | $53.12 | Investment bars, rounds, and industrial stock; rarely used for jewelry. |
| Pt950 | 0.950 fine | $50.52 | The jewelry standard. Marked Pt950, PLAT950, 950 PLAT, or simply PLAT on most US and European rings. |
| Pt900 | 0.900 fine | $47.86 | Older US rings and 90% platinum / 10% iridium settings; marked Pt900 or 900 PLAT. |
| Pt850 | 0.850 fine | $45.20 | Chains, lighter settings, and some imported work; marked Pt850 or 850 PLAT. |
The transparent formula
Each row equals the visible market value per troy ounce × its unit conversion × its purity or recovery factor. Change the input and every row recalculates in your browser.
Calculate a specific platinum item's melt value and compare a buyer quote.
Match the platinum row to a verified fineness
The FTC Jewelry Guides distinguish an unqualified Platinum description from representations that state parts per thousand platinum and, when applicable, other platinum-group-metal content. Use the complete representation and verified composition; a mark is an identification clue, not an assay.
Platinum price per gram does not value a catalytic converter
The U.S. Department of Energy describes converters as substrates carrying a variable mix of platinum-group metals. Use the table for verified platinum-bearing weight, not the complete converter, and obtain a specialist converter assessment.

Frequently asked questions
What is the platinum price per gram today?
The displayed reference value is $53.18 per gram until the live feed updates or you edit the market price. Prices move continuously, so confirm the timestamp and input before transacting.
How is platinum price per gram calculated?
MeltOffer converts the visible market price per troy ounce using exact unit factors, then multiplies by purity where applicable. Every value on this page updates from the same editable input.
Will a buyer pay the full platinum reference price?
Usually not. The reference price values contained metal before testing, handling, refining, and buyer margin. Use the platinum calculator to compare a written quote.
How is the .950 platinum price per gram calculated?
Divide the platinum reference price per troy ounce by 31.1035, then multiply by 0.95. Apply that row only to verified .950 platinum-bearing weight.
Can I multiply catalytic-converter weight by platinum price?
No. A converter is not solid platinum; its substrate and variable multi-metal loading require specialist identification and recovery terms.
