Convert gold weight between grams and pennyweight in either direction. Choose the conversion you need, enter the weight, and calculate the equivalent value using the standard relationship of 1 pennyweight (DWT) = 1.55517384 grams.
Convert grams to pennyweight or pennyweight to grams.
Pennyweight is a mass unit. Gold purity does not change the basic grams-to-pennyweight conversion.
A pennyweight, abbreviated DWT, is a traditional precious metal weight unit. One pennyweight equals exactly 1.55517384 grams.
To convert grams into pennyweight, divide the gram weight by 1.55517384.
For example, 10 grams of gold converts to approximately 6.43015 pennyweight.
To convert pennyweight into grams, multiply the pennyweight value by 1.55517384.
For example, 10 pennyweights of gold equals:
| Gold Weight | Pennyweight |
|---|---|
| 1 gram | ≈ 0.643015 DWT |
| 5 grams | ≈ 3.215075 DWT |
| 10 grams | ≈ 6.43015 DWT |
| 15 grams | ≈ 9.645225 DWT |
| 20 grams | ≈ 12.86030 DWT |
| 31.1034768 grams | 20 DWT |
| 50 grams | ≈ 32.15075 DWT |
| 100 grams | ≈ 64.30150 DWT |
Pennyweight is a traditional unit of mass used particularly in jewellery and precious-metal contexts. Its abbreviation is DWT.
One pennyweight is equal to 1/20 of a troy ounce. Since one troy ounce is 31.1034768 grams, one pennyweight is:
Pennyweight is directly connected to the troy-ounce system used for precious metals. There are exactly 20 pennyweights in one troy ounce.
| Unit | Equivalent |
|---|---|
| 1 pennyweight | 1.55517384 g |
| 5 pennyweights | 7.7758692 g |
| 10 pennyweights | 15.5517384 g |
| 20 pennyweights | 31.1034768 g |
| 20 pennyweights | 1 troy oz |
This relationship makes pennyweight particularly useful when working with jewellery weights that are expressed in the traditional troy system.
No. Pennyweight is a unit of mass, so its conversion to grams remains the same regardless of whether the gold is 24K, 22K, 18K, 14K or another fineness.
Purity affects the amount of actual gold contained within an alloy, not the mass represented by a pennyweight.
For example, 10 DWT has a gross mass of 15.5517384 grams regardless of purity. If that material were 18K, the approximate fine-gold content would be calculated separately using the appropriate purity fraction.
Pennyweight has historically been used extensively in jewellery and precious-metal work. Jewellery businesses may encounter DWT when recording metal weights, estimating material requirements or discussing precious metal quantities.
Converting DWT to grams can make traditional jewellery measurements easier to use alongside metric inventory records.
When a jeweller knows the metal weight in DWT, the gram equivalent can be calculated directly using the standard conversion.
Converting both measurements into grams can simplify comparisons when different suppliers or records use different weight units.
| Unit | Grams |
|---|---|
| 1 gram | 1 g |
| 1 pennyweight | 1.55517384 g |
| 1 tola | 11.6638125 g |
| 1 troy ounce | 31.1034768 g |
| 1 kilogram | 1,000 g |
These are weight relationships. They should be kept separate from gold purity, fineness and price calculations.
Gold and jewellery prices can be quoted using different units. Before comparing prices, identify whether the quoted price is per gram, per pennyweight, per troy ounce or another unit.
A price quoted per pennyweight can be converted to an equivalent price per gram by dividing the pennyweight price by 1.55517384.
Conversely, a gram-based price can be converted into a price per pennyweight by multiplying it by 1.55517384.
When comparing jewellery prices, also account for purity, labour charges, premiums, taxes and other applicable costs.
This calculator converts weight only. It does not determine gold purity, authenticity, market value, dealer buyback value or jewellery-making charges.
It does not use live gold prices. A weight conversion should therefore be treated separately from any gold valuation or pricing calculation.
For physical gold and jewellery, use verified scale measurements and reliable fineness or assay information for product-specific decisions.
One pennyweight equals exactly 1.55517384 grams.
Divide the weight in grams by 1.55517384.
Multiply the pennyweight by 1.55517384.
DWT is the standard abbreviation for pennyweight.
No. Pennyweight is a mass unit, so the conversion is independent of purity.
One troy ounce equals exactly 20 pennyweights.
10 pennyweights equals 15.5517384 grams.
No. It converts weight only and does not require a gold price.
