Silver by Weight: Complete Unit Conversion Guide with Live Values
Silver gets quoted, weighed, and sold in seven different units depending on who you ask: grams, troy ounces, pounds, pennyweight, kilos, tola. Mix any two of them up and you can lose 8%, 10%, even 21% of your money. This silver weight chart maps every unit to every other unit in one place, with real worked examples and the South Asian units (tola, masha, bhori) that most Western guides skip.
What Is the Weight of Silver in Grams?
Here is the strange truth about this metal: the global price is quoted in one unit (the troy ounce), but almost no one actually weighs their pieces in troy ounces. Jewelers use grams. Bulk sellers use pounds. Refiners sometimes use pennyweight. South Asia uses tola. Bullion bars come in kilos. And the everyday kitchen ounce is not even the same as the troy ounce that silver is priced in.
That mismatch is exactly where money disappears. If you weigh a sterling necklace on a kitchen scale (avoirdupois ounce) and a buyer calculates using troy ounces, the value swings by about 10% before any negotiation. Knowing the correct weight in grams, and which unit buyers actually pay on, is the difference between getting paid right and getting shortchanged. This is the reference chart that fixes all of it.

Grams to Troy Ounces: Silver Weight in Grams Converted
The most common conversion you will run is grams to troy ounces, because this metal is priced per troy ounce but jewelry scales read in grams. The math is simple: divide grams by 31.1035. Memorize that one number and you can convert any gram figure to troy ounces in your head.
Troy ounces: 48 ÷ 31.1035 = 1.5432 troy oz
Apply sterling purity (.925): 1.5432 × 0.925 = 1.4275 troy oz of pure metal
At $75/oz spot: 1.4275 × $75 = $107.06 melt value
So your 48g sterling chain carries a melt value of about $107.06. In Canadian dollars at 1.37, that is roughly C$146.67.
This is the same division a per-gram tool runs in the background. For a full reference table of every gram weight from 1g to 1000g with value at each step, our per-gram calculator guide lays it out in detail.
Troy Ounces to Grams: Verifying a Bar
The reverse conversion comes up when you are shopping for bullion. A "10 oz bar" usually means 10 troy ounces, and you want to know what that should weigh in grams, because that is how your scale at home reads. Multiply troy ounces by 31.1035 to get grams.
Expected grams: 10 × 31.1035 = 311.04 g
Your scale reads: 305 g
Difference: 6 g short, about 2% under what you paid for.
A 0.5g tolerance is normal. Six grams short means the bar may be counterfeit or you are being shortchanged. Always verify the actual weight before accepting.
This same conversion lets you sanity check any quote given by weight. If a dealer quotes "$85 per ounce" for sterling, ask whether that is troy or avoirdupois, because the difference is about 10%. For a deeper walkthrough of scales, calibration and stripping out non-metal parts, see our guide on how to weigh silver accurately.
Pennyweight (DWT): The Coin-Shop Unit
Pennyweight, abbreviated dwt, is an older unit you will still hear at coin shops and older refineries. One pennyweight equals 1.55517 grams, or exactly one twentieth of a troy ounce. The name comes from the medieval English penny, which historically weighed one pennyweight.
The per-dwt value scales directly with spot, so the table below moves as the market moves. It uses a band around the current teaching value so you can read across whatever the market is doing that week.
| Purity | Per DWT @ $70/oz | Per DWT @ $75/oz | Per DWT @ $80/oz |
|---|---|---|---|
| Fine .999 | $3.50 | $3.75 | $4.00 |
| Sterling .925 | $3.24 | $3.47 | $3.70 |
| Coin .900 | $3.15 | $3.38 | $3.60 |
Pennyweight prices scale linearly with spot. If a refiner offers well below these per-dwt figures, they are taking a large cut.
Pounds and Kilos: Converting the Bulk Units
When pieces get sold by the pound (estate sales, flatware lots, scrap dealers), you convert to grams or troy ounces to check the price. There are two pounds, and using the wrong one distorts the math by about 21%.
- Avoirdupois pound (everyday lb): 453.592 g = 14.5833 troy oz
- Troy pound (historic): 373.242 g = 12.0000 troy oz
- Kilogram (bullion bars): 1,000 g = 32.1507 troy oz
For modern transactions, assume the avoirdupois pound unless the seller specifically says "troy pound." Quoting by the pound rather than per troy ounce is common in scrap and estate lots, and it is where confusion creeps in. This chart handles the unit conversion; for the full melt-value math, worked pound by pound with live figures, see our dedicated silver per pound guide.
Tola, Masha and Bhori: South Asian Units
In South Asia (India, Pakistan, Bangladesh, Nepal) both silver and gold have been traded in tola for centuries. The tola is a fixed weight: 11.6638 grams, which works out to exactly three eighths of a troy ounce. So 8 tola = 3 troy ounces. Knowing this conversion is essential if you are buying in any South Asian market.
The tola breaks down into smaller and larger units:
- 1 masha = 0.9719 g = one twelfth of a tola (used for very small jewelry)
- 1 tola = 11.6638 g (the everyday unit)
- 1 bhori = 10 g (used in Bangladesh; close to but not the same as tola)
- 1 chittak = 5 tola = 58.32 g (older Indian unit, less common now)
- 1 ser/seer = 80 tola = 933.10 g (historical, rare today)
If you are in Karachi, Mumbai or Dhaka, the local scale almost certainly reads tola or bhori rather than grams, so you will need to convert before using any international calculator that defaults to grams or troy ounces.
How the Unit Changes the Value by Weight
The unit you use does not change how much metal you hold, but it changes how the price gets calculated, and that is where people lose money. Here is the same 100 grams of fine silver, priced through five different unit systems at $75/oz spot:
| Quote Method | Equivalent | Value at $75/oz |
|---|---|---|
| Per gram | 100 × $2.4113 | $241.13 |
| Per troy ounce | 3.2151 × $75.00 | $241.13 |
| Per pennyweight | 64.301 × $3.75 | $241.13 |
| Per tola | 8.575 × $28.13 | $241.21 |
| Per avoirdupois oz (WRONG) | 3.527 × $75.00 | $264.53 |
Same 100g, different unit math. Rounding aside, every correct method lands on about $241.13. Using the regular avoirdupois ounce inflates the figure by roughly 10%.
This is why the unit matters so much when selling by weight. The value is fixed by the metal content, but the unit decides whether you and the buyer end up on the same number. Mismatch the units and one of you walks away wrong. For value laid out across every weight and purity in one place, see our complete silver value guide.
Silver Weight Measurement: Grams First, Then Convert
Across every unit above, one workflow keeps you accurate: record the weight in grams first, then convert to whatever unit the buyer uses. Grams give the finest precision and are the cleanest input for any calculator, and they remove the troy-versus-regular ambiguity entirely until the final step.
So the reliable silver weight measurement routine is: weigh in grams on a 0.1g scale, group items by purity, divide grams by 31.1035 for troy ounces, then apply purity and spot. If you are working with sterling specifically, hallmarks and payout ranges are covered in our sterling .925 value guide. Do the units in that order and no dealer can quietly move you onto the wrong one.
Three Numbers That Solve Almost Everything
This metal is one material but many units, and the unit you use decides whether you and your buyer land on the same number. Memorize three facts and you have solved most of it: 1 troy oz = 31.1035 g, 1 lb (avoir) = 453.59 g, and 1 tola = 11.6638 g. Everything else in the chart flows from those three.
Whether you are weighing a chain on a jewelry scale, pricing a small estate lot, or reading a tola quote in a South Asian market, the math is always the same once the units line up. Lock that in, weigh in grams, convert deliberately, and no buyer can shortchange you on weight.
Common Questions About Silver Weight
What is the weight of silver in grams per troy ounce?
One troy ounce is exactly 31.1035 grams, slightly heavier than the everyday avoirdupois ounce (28.3495 g). Every spot price you see, on COMEX, the LBMA or dealer sites, is quoted per troy ounce, not the regular ounce. Always confirm "troy ounce" when buying or selling, because mixing the two units changes the value by about 10%.
How do I convert silver weight from grams to troy ounces?
Divide grams by 31.1035 to get troy ounces, the unit this metal is priced in. For example, 100 grams ÷ 31.1035 = 3.215 troy ounces. Do not divide by 28.35, because that is the avoirdupois ounce and it will overvalue your pieces by about 10%. Any reliable converter uses 31.1035 as the factor.
How many grams are in a pound of silver?
A standard avoirdupois pound holds 453.592 grams, the everyday US pound. A troy pound is only 373.242 grams (12 troy ounces). Most consumer transactions use the avoirdupois pound, so 453.592 g is the figure to remember when someone quotes by the pound. The troy version is about 18% lighter, so always ask which one a dealer means.
What is a pennyweight (DWT) and how heavy is it?
A pennyweight (dwt) is an old precious metals unit equal to 1.55517 grams, or one twentieth of a troy ounce. It comes from the medieval English penny, and coin shops and older refiners still quote in it. At $75/oz spot, one pennyweight of fine metal is worth $3.75. To convert any per-dwt quote to per-gram, divide by 1.55517.
What is a tola in weight terms?
A tola is the traditional South Asian unit, equal to 11.6638 grams or exactly three eighths of a troy ounce. It is still standard in jewelry markets across India, Pakistan, Bangladesh and Nepal. At $75/oz spot, one tola of fine metal is worth about $28.13, and a sterling tola is around $26.02. Most South Asian scales read in tola directly.
What are the main units silver is measured in?
The core silver measurement units are the gram (jewelry and scrap), the troy ounce (global pricing), the pennyweight (coin shops), the avoirdupois and troy pound (bulk lots), the kilogram (bullion bars), and the tola, masha and bhori (South Asia). The troy ounce at 31.1035 g is the anchor, since every value calculation ultimately runs through it.
How is silver weight measured accurately at home?
Weigh in grams on a digital scale that reads to 0.1 g or finer, place it on a hard level surface, and group items of the same purity together. Record the gram figure, then divide by 31.1035 to reach troy ounces for pricing. Removing stones, clasps and steel blades first keeps the number honest. Our dedicated weighing guide covers scales, calibration and cleanup in full.
Is a troy ounce the same as a regular ounce?
No, and this catches almost everyone. A regular avoirdupois ounce is 28.3495 grams. A troy ounce is 31.1035 grams, about 10% heavier. Silver, gold and platinum are always priced per troy ounce. Food, packages and everyday items use the avoirdupois ounce. Confuse them and the same pieces appear 10% more valuable than they really are.
Why does the weight unit matter when selling?
Because mismatched units can shift the perceived value by up to 21%. A pound can mean two weights (avoirdupois or troy). An ounce can mean two weights (regular or troy). A buyer quoting one while a seller uses another creates a real money gap. Confirm the unit before agreeing a price, and use only the troy ounce for pricing.
How do I convert a kilo bar into troy ounces?
One kilogram equals 32.1507 troy ounces (1,000 ÷ 31.1035). So a 1 kg bar of fine metal at $75/oz spot has a melt value of about $2,411. A kilo bar also equals 2.2046 avoirdupois pounds. Because bullion bars are stamped in grams or kilos, this conversion lets you check a bar's melt value against the dealer's asking price before any premium.
