- Multiply the gram price by a thousand to get the kilogram value.
- Check silver purity and dealer premiums before comparing a shop price.
Start with the silver ounce price
Use the silver spot price per troy ounce, with the currency set to US dollars. The quote is $53.92 at 23 Oct 2026, 21:08 UTC. A troy ounce contains 31.1035 g, so the ounce quote can be converted directly into a gram value.
Check that another quote uses a troy ounce before comparing it. Weight units, purity and price time must match. A price for a finished silver item can also include charges that are separate from the metal content.
Divide for the gram price
Divide the dollar amount of $53.92 by 31.1035 to get $1.734 per gram. The silver gram price uses three decimal places because the amount is small and rounding can affect a weight calculation.
The ounce quote is rounded to the cent, and the gram price is worked from it. Use that gram price for longer weights. This keeps each calculation traceable to the same quote.
Multiply for grams and kilograms
Multiply the gram price by your weight in grams. This gives $17.34 for ten grams and $173.40 for a hundred grams. A kilogram contains a thousand grams, giving a silver value of $1,734.00.
Use the weight of the silver you are valuing, with its purity accounted for. The value covers pure silver content. If an item includes other metals or materials, its whole weight does not represent the same weight of pure silver.
| Weight | Grams | Silver price |
|---|---|---|
| Troy ounce | 31.1035 g | $53.92 |
| Gram | 1 g | $1.734 |
| 10 grams | 10 g | $17.34 |
| 100 grams | 100 g | $173.40 |
| Kilogram | 1,000 g | $1,734.00 |
Check purity and dealer premiums
Sterling silver is commonly marked nine hundred and twenty five. The stamp indicates its silver purity, so a sterling item's full weight should not be valued as pure silver. Account for the silver share before applying the pure silver gram price.
Silver bars and coins sell above their spot metal value because a dealer premium is added. Jewellery can also include making charges, and tax may add to the bill. Ask for those amounts separately when checking a seller's total.
Request the silver kilo value from the API
The convert request below asks for the US dollar value of a kilogram of silver. Use it to check a weight conversion. For the starting ounce price, request the silver spot endpoint instead and divide that quote by 31.1035.
Both keyless requests work without sign-up and return prices 15 minutes late. The limit is 100 requests an hour. A free key allows 5,000 calls a month. Compare quote times and allow for display rounding when checking the result.
