Silver Price Per Gram Explained
The silver spot price is quoted globally in troy ounces, but most people want to know the price per gram — especially when valuing jewellery, silverware, or scrap silver. This guide explains exactly how the silver price per gram is derived, what different silver purities are worth, and how to calculate the value of silver items you own.
How Is the Silver Price Per Gram Calculated?
The silver spot price is the internationally traded price for one troy ounce of 99.9% pure silver. Since 1 troy ounce = 31.1035 grams, you can always convert to a per-gram price with a simple division:
For example, if silver is trading at $32.50 per troy ounce, then the price per gram is $32.50 ÷ 31.1035 = $1.045 per gram.

Tip: Silver is significantly cheaper per gram than gold — typically by a factor of 80–90x. This makes it accessible for smaller purchases but also means silver items need to be weighed accurately to determine meaningful value.
Silver Purity Grades and Hallmarks
Like gold, silver comes in different purity grades. The value of a silver item depends on both its weight and its purity:
| Grade | Purity | Hallmark | Common Uses |
|---|---|---|---|
| Fine Silver | 99.9% | .999 / 999 | Bullion bars, coins, investment silver |
| Britannia Silver | 95.84% | .958 / 958 | UK silverware, some coins |
| Sterling Silver | 92.5% | .925 / 925 | Jewellery, cutlery, tableware worldwide |
| Coin Silver (US) | 90.0% | .900 / 900 | Pre-1965 US coins, some jewellery |
| 800 Silver | 80.0% | .800 / 800 | European silverware, older jewellery |
What Is Sterling Silver Worth Per Gram?
Sterling silver (.925) is the most common form of silver jewellery and silverware. Its value per gram is calculated by multiplying the pure silver spot price per gram by the purity factor of 0.925:
How to Value Silver Jewellery and Coins
To calculate the melt value of any silver item:
- Identify the purity (check for a hallmark stamp: 925, 999, 800, etc.)
- Weigh the item accurately in grams on a digital scale
- Note the current silver spot price per gram (or use our calculator)
- Multiply: Weight × Purity Factor × Spot price per gram
Note that dealers buying scrap silver typically pay 60–80% of melt value, since they factor in refining costs.
Silver Coins — Bullion vs Numismatic Value
Silver coins have two potential values: their melt value (based on silver content) and their numismatic (collector) value (based on rarity, condition, and demand). Common modern bullion coins like the American Silver Eagle (1 troy oz, .999 silver) or the UK Britannia are typically worth close to spot price. Rare or old coins may be worth significantly more than their melt value — consult a coin dealer before selling these as scrap.
Factors That Affect the Silver Spot Price
Silver is both a precious metal and an industrial metal, which gives it a dual demand profile. Key price drivers include:
- Industrial demand: Silver is essential in solar panels, electronics, and electric vehicles, driving significant industrial consumption
- Investment demand: Silver ETFs and physical silver buying increase during periods of economic uncertainty
- Gold/silver ratio: The ratio of the gold price to the silver price (typically 60–90x) is closely watched by precious metals investors
- US dollar strength: Like gold, silver prices tend to move inversely to a strong US dollar
- Mining supply: Around 70% of silver is produced as a by-product of mining other metals like copper and zinc
