Free Silver Price per Gram Calculator
Convert a silver price per troy ounce, kilogram, 100 grams, 10 grams or other unit into comparable per-gram rates. See 999 fine, 990, 970, 958, 925 sterling, 900, 835 and 800 silver prices in your selected currency.
Silver Rate per Gram Converter
Enter a current silver quote, its unit and purity basis. The default market basis treats the quote as one troy ounce of 999 silver, consistent with the wholesale silver convention.
| Silver fineness | Purity | Price per gram | Price per 10 g |
|---|
Rates use the entered unit, source purity and adjustment.
This calculator does not fetch or redistribute a live silver benchmark. Results exclude fabrication, mint premium, delivery, tax and dealer spread unless represented by the single adjustment percentage.
Reviewed on 15 July 2026 using NIST weight conversions, Bureau of Indian Standards and UK hallmarking guidance, and LBMA silver-market conventions.
A silver price per gram makes rates quoted in troy ounces, kilograms and regional weight units easier to compare. This calculator normalizes the entered quote for its purity basis, converts it to grams, and derives standard fineness rates without claiming to supply today's live silver price.
Silver Price per Gram Formula
First divide the entered quote by the number of grams in its unit. Then normalize for the source fineness and multiply by the desired fineness.
Purity percentages must use the same scale. For example, 999 is 99.9% and 925 is 92.5%.
Silver Price per Troy Ounce to Per Gram
NIST gives one troy ounce as exactly 31.1034768 grams. For a quote already expressed for 999 silver and a 999 output rate:
No extra 999 multiplier is needed when the source and target fineness match. The purity ratio is 999/999, which equals one.
Silver and Gold Use Different Market Conventions
LBMA explains that gold is quoted per fine troy ounce, while silver is quoted per troy ounce of material meeting a minimum 999 fineness. Therefore, the calculator defaults to a 999 silver market quote—not a theoretical 100% pure-silver quote.
If your source explicitly gives a theoretical pure-silver rate, select 100%. If it gives a direct 925 sterling price, select 925 so the target conversion does not apply purity twice.
999 Silver Price per Gram
For a 999 quote, divide the amount by its gram-equivalent unit. Common conversions are:
- Per troy ounce: divide by 31.1034768
- Per kilogram: divide by 1,000
- Per 100 grams: divide by 100
- Per 10 grams: divide by 10
The calculator also supports a regular avoirdupois ounce and pound, but these should be chosen only when the source explicitly uses everyday weight units.
925 Sterling Silver Price per Gram
To estimate a 925 rate from a 999 rate, multiply by the purity ratio:
This estimates silver-content value only. A finished sterling item can sell above or below this rate because of manufacturing, design, brand, condition, tax, dealer spread and demand.
Silver Fineness Rates Used
| Silver grade | Purity | Rate from normalized 100% reference |
|---|---|---|
| 999 fine silver | 99.9% | Reference × 0.999 |
| 990 silver | 99.0% | Reference × 0.990 |
| 970 silver | 97.0% | Reference × 0.970 |
| 958 Britannia silver | 95.8% | Reference × 0.958 |
| 925 sterling silver | 92.5% | Reference × 0.925 |
| 900 silver | 90.0% | Reference × 0.900 |
| 835 silver | 83.5% | Reference × 0.835 |
| 800 silver | 80.0% | Reference × 0.800 |
BIS guidance lists 990, 970, 925, 900, 835 and 800 for Indian silver hallmarking under IS 2112:2014. UK guidance recognizes descriptions including 999 fine, 958 Britannia and 925 sterling. Marks and legal requirements vary by jurisdiction.
Worked Silver Price per Gram Example
Assume an illustrative USD 35 price per troy ounce of 999 silver with no premium or discount:
- 999 price per gram = USD 35 / 31.1034768 = about USD 1.125276
- 925 price per gram = USD 1.125276 × 925 / 999 = about USD 1.041922
- 900 price per gram = about USD 1.013762
- 800 price per gram = about USD 0.901122
USD 35 is a round worked input, not a current silver quote.
Premium or Discount Adjustment
The optional adjustment applies one percentage after unit and purity conversion. Use a positive value for a premium and a negative value for a discount.
This field does not separately calculate tax, fabrication, shipping, assay cost or dealer spread. Avoid adding a charge that is already included in the source price.
Per-Gram Rate vs Total Silver Value
This page converts rates only. It does not ask for item weight, quantity or dealer payout. To calculate the total worth of an item or collection, use the Silver Value Calculator with net weight and fineness.
