Free Silver Weight Converter
Convert silver weight between grams, kilograms, troy ounces, regular ounces, regular pounds, troy pounds, pennyweight, grains and tola. One entry produces the selected conversion and every supported equivalent.
Silver Weight Unit Converter
Convert silver mass only. Troy ounces and regular avoirdupois ounces—and troy pounds and regular pounds—are labeled separately.
Precious-metal “ounce” usually means a troy ounce. This tool never treats a regular ounce or pound as a troy unit unless you select that unit explicitly.
This calculator converts mass only. It does not determine silver purity, fine-silver content, melt value, price, premium, dealer payout or assay result.
Reviewed on 15 July 2026 using NIST Handbook 44 mass tables, LBMA silver-market conventions and official Royal Mint silver specifications.
Silver is weighed in both metric and customary units. Bullion prices and large wholesale bars commonly use troy ounces, while scrap, shipping and household scales may use grams, kilograms, regular ounces or regular pounds. This converter makes the unit definition explicit before converting.
How the Silver Weight Converter Works
The calculator uses grams as a common internal bridge. It multiplies the entered amount by the source unit's gram factor, then divides that gram result by the target unit's factor.
Calculations retain the unrounded numeric result. Display values use up to ten decimal places, with scientific notation for extremely small or large results.
Silver Weight Conversion Factors
| Unit | Symbol | Grams used | Relationship |
|---|---|---|---|
| Gram | g | 1 | Base unit used by this converter |
| Kilogram | kg | 1,000 | 1 kg = 1,000 g |
| Troy ounce | ozt | 31.1034768 | 1 ozt = 20 dwt = 480 grains |
| Regular ounce | oz | 28.349523125 | 16 oz = 1 regular pound |
| Regular pound | lb | 453.59237 | 16 regular oz = 7,000 grains |
| Troy pound | lb t | 373.2417216 | 12 troy oz = 5,760 grains |
| Pennyweight | dwt | 1.55517384 | 24 grains; 20 dwt = 1 ozt |
| Grain | gr | 0.06479891 | 480 grains = 1 ozt |
| Tola | tola | 11.6638038 | Conventional 180-troy-grain basis |
NIST's 2026 tables define the troy relationships of 24 grains per pennyweight, 20 pennyweights per troy ounce and 12 troy ounces per troy pound. They separately define the avoirdupois system as 16 regular ounces and 7,000 grains per regular pound.
Troy Ounce vs Regular Ounce
LBMA silver market conventions express the silver price per troy ounce. Do not convert a precious-metal quote with the 28.3495-gram regular-ounce factor unless the source explicitly says it uses an avoirdupois ounce.
Regular Pound vs Troy Pound
A regular pound and a troy pound are different masses:
- 1 regular pound = 453.59237 grams = approximately 14.5833333333 troy ounces
- 1 troy pound = 373.2417216 grams = exactly 12 troy ounces
- 1 regular pound is therefore heavier than 1 troy pound
Pennyweight, Grain and Tola
Pennyweight and grain belong to traditional precious-metal measurement. Twenty pennyweights equal one troy ounce, and each pennyweight contains 24 grains. The grain is common to troy and avoirdupois relationships even though the larger units differ.
This page uses the conventional 180-troy-grain tola:
Some retail listings may use “tola” loosely for a 10-gram product. This converter does not: select grams when a product is explicitly marked 10 g.
Worked Silver Weight Examples
The Royal Mint's one-kilogram silver bar specification lists pure metal content as approximately 32.15 troy ounces, consistent with the kilogram-to-troy-ounce conversion after display rounding.
Total Weight vs Fine-Silver Content
Unit conversion does not change or determine purity. A 100-gram sterling-silver item and a 100-gram 999 silver bar have the same total mass but different fine-silver content. Likewise, stones, handles, fillers, packaging and non-silver components can be part of a gross measured weight.
Use an item's documented pure metal content when available, or use the appropriate value or melt calculator to apply fineness. This converter intentionally has no price or purity field.
Scale Accuracy and Rounding
- Use a scale with enough capacity and resolution for the item or lot.
- Tare containers, trays and packaging before recording net weight.
- Confirm whether the display unit is g, kg, oz, lb, ozt or dwt.
- Keep unrounded results until the final reporting or pricing step.
- Remember that displayed decimal places do not improve the physical scale's accuracy.
