Silver Price per Gram Today

The kitchen-scale error that inflates silver by the gram

To get the silver price per gram, divide the troy-ounce spot price by 31.1035. The most common mistake runs the other way: someone weighs a bracelet on a kitchen scale set to ounces, then multiplies by the troy price.

A kitchen ounce is the avoirdupois ounce, 28.3495 grams. A troy ounce is about 9.7% heavier. So 100 grams reads as 3.53 ounces on the kitchen scale but is only 3.215 troy ounces. Multiply the wrong figure by spot and you overstate the value by nearly a tenth. Setting the scale to grams avoids the whole problem.

Why grams are the better unit for small silver

Jewelry, chains and single spoons often weigh between 5 and 60 grams. At that size, rounding to a tenth of an ounce throws away about three grams. Jewelers’ scales read to 0.01 g, and so do the scales most buyers use at the counter.

Getting a trustworthy gram reading

• Use a scale that reads to at least 0.1 g, and 0.01 g for rings and earrings.
• Check it against a known weight. A U.S. nickel minted since 1866 is specified at 5.000 grams, which makes a handy test weight.
• Press tare with any dish on the scale, then add the silver.
• Weigh chains coiled in the center of the pan, not draped over the edge.

Per-gram values at an example price

The table uses a fixed example of $30 per troy ounce so the arithmetic is easy to follow. The live figures at the top of the page use today’s spot.

Worked example: a 42-gram sterling cuff

1. Start from the example spot: $30 ÷ 31.1035 = $0.9645 per gram of pure silver.
2. Apply sterling purity: $0.9645 × 0.925 = $0.8922 per gram.
3. Multiply by weight: 42 g × $0.8922 = about $37.47 of silver content.

That $37.47 is metal value only. A buyer will offer a share of it, and a retail store may ask far more because of design and labor.

Worked example: pricing per pennyweight

Scrap buyers in the U.S. often quote by the pennyweight (dwt), which is 1.5552 grams. Multiply the per-gram figure by 1.5552 to switch. At the example spot, fine silver is $0.9645 × 1.5552 = about $1.50 per dwt, and sterling about $1.39 per dwt. If a buyer quotes per pennyweight and you compare it with a per-gram price, the numbers look about 55% apart even when they are the same offer.

Worked example: 100 grams of old coin-silver spoons

American spoons made before sterling became the national standard were often coin silver, 90% pure. At the same example price, 100 grams × $0.8681 gives $86.81 of silver. A common trap here: some coin-silver spoons are marked only with a maker’s name, so the purity has to be confirmed by testing before the 0.900 multiplier is safe to use.

What trims the payable weight on silver jewelry

Scale weight and silver weight are rarely the same on finished pieces. Before multiplying by the per-gram figure, take out what isn’t silver.

Deductions buyers make

• Stones, pearls and glass are removed or estimated and deducted before the gram count.
• Many sterling chains use a steel spring inside the clasp, and some findings are plated base metal.
• A “925” stamp on a clasp does not prove the chain is sterling. Check the links too, because replacement clasps are common.
• Rhodium or gold plating on sterling adds almost no weight, and a refiner pays nothing extra for it.
• Marcasite jewelry is set with many small pyrite stones glued in place, which inflate the weight.

Less common fineness numbers

Older and foreign pieces use purities that don’t appear in the table above. Each one simply changes the multiplier.

• 830 or 830S: widely used in Scandinavian silver. Multiply by 0.830.
• 835: common on older German and Dutch pieces. Multiply by 0.835.
• 950: the French first standard, often with a Minerva head hallmark. Multiply by 0.950.
• 84 with Cyrillic marks: the Russian zolotnik system, 84 parts of 96, equal to 0.875.

Gram bars and the premium curve

Silver bars are also sold by the gram. A 1-kilogram bar holds 32.15 troy ounces, and a 100 g bar about 3.215 oz. The smaller the bar, the higher its premium per gram, because the cost of making and packaging a bar barely shrinks with its size.

Comparing a kilo bar with one-ounce coins

To compare the two fairly, turn both into a cost per gram of pure silver: divide each item’s price by its fine weight in grams. A kilo bar divides by 1,000, a one-ounce coin by 31.1035. The lower number is the cheaper silver, before any difference in how easy each is to resell.

How other markets quote silver by weight

The U.S. market thinks in troy ounces. Much of the world quotes silver per kilogram, and a few markets use traditional units.

Local prices abroad also include import duties and taxes that the U.S. dollar spot price leaves out. In most European Union countries, silver bullion is charged standard VAT, while investment gold is exempt. That is one reason a gram of silver bought in Europe can cost noticeably more than the spot conversion suggests.

Converting a foreign per-kilo quote

1. Convert the local price per kilogram into dollars at the current exchange rate.
2. Divide by 1,000 to get dollars per gram.
3. Compare with the per-gram figure at the top of this page. The difference is roughly the local tax, duty and dealer margin.

Expect the gap to change from week to week, because exchange rates and local premiums move independently of spot.

Travelers sometimes buy silver jewelry abroad and assume the gram price there reflects metal value. In tourist markets, the price per gram usually bundles in design and labor, so it can run several times the melt value of the silver. The per-gram figure here is the floor, not a fair retail price.

Short glossary

• Fine silver: 99.9% pure silver, the basis of every spot quote.
• Pennyweight (dwt): 1/20 of a troy ounce, used by jewelers and scrap buyers.
• Melt value: the worth of the pure silver in an item at spot, before any buyer’s margin.
• Premium: what a seller charges above melt value for a coin or bar.

For coins with fixed silver contents, the junk silver calculator does the per-gram math for you.

The main silver price page shows ounce and kilogram quotes side by side.

Gold follows the same per-gram logic on our gold price per gram page, with karat multipliers in place of silver fineness.

If you track both metals, the gold price per ounce today converts the same way: divide by 31.1035 for a gram figure.
