Grams to dwt Converter
This calculator helps you convert g to dwt, this conversion is particularly useful in fields such as jewelry making, precious metal trading.
Grams are a metric unit of mass widely used in scientific and everyday contexts. They are part of the International System of Units (SI) and represent one-thousandth of a kilogram.
Pennyweight, abbreviated as dwt, is a unit of mass that is part of the troy weight system. It is primarily used in the precious metals industry, especially for weighing gold, silver, and gemstones. The term “pennyweight” originated from the weight of a silver penny in medieval England.
How do you Convert Grams to dwt?
Converting grams to pennyweights (dwt) involves a simple mathematical calculation.
- Know the conversion factor: 1 gram is equal to approximately 0.643014931 pennyweights.
- Multiply the gram value by the conversion factor: To convert grams to dwt, multiply the number of grams by 0.643014931.
For example, to convert 10 grams to pennyweights: 10 grams × 0.643014931 = 6.43014931 dwt
- 0.3 grams to dwt = 0.19290448 dwt
- 1 gram to dwt = 0.64301493 dwt
- 1.5 grams to dwt = 0.96452240 dwt
- 2 grams to dwt = 1.28602986 dwt
- 2.5 grams to dwt = 1.60753733 dwt
- 2.8 grams to dwt = 1.80044181 dwt
- 3 grams to dwt = 1.92904479 dwt
- 3.4 grams to dwt = 2.18625077 dwt
- 3.6 grams to dwt = 2.31485375 dwt
- 3.9 grams to dwt = 2.50775823 dwt
- 1000 grams to dwt = 643.01493088 dwt
Grams To Pennyweight Conversion Formula
The formula for converting grams to pennyweights is:
dwt = grams × 0.643014931
This formula is derived from the relationship between grams and troy ounces, as well as the definition of a pennyweight within the troy weight system.
To break it down further:
- 1 troy ounce = 31.1034768 grams
- 1 troy ounce = 20 pennyweights
- Therefore, 1 pennyweight = 31.1034768 ÷ 20 = 1.55517384 grams
- The inverse of this gives us the conversion factor: 1 ÷ 1.55517384 ≈ 0.643014931
How much does a dwt weigh?
A pennyweight (dwt) has a specific weight within the troy weight system. One pennyweight is equal to:
- 1.55517384 grams
- 0.05 troy ounces
- 24 grains
To put this into perspective, a pennyweight is slightly heavier than a standard paperclip, which typically weighs about 1 gram.
The weight of a pennyweight is carefully standardized to ensure consistency in measurements, particularly in the precious metals and jewelry industries.
Is dwt the same as grams?
No, dwt (pennyweight) is not the same as grams. They are two distinct units of mass measurement belonging to different systems:
- Dwt (pennyweight) is part of the troy weight system, primarily used for precious metals and gemstones.
- Grams are part of the metric system, used more broadly in scientific and everyday measurements.
Both measure mass, they have different magnitudes and are used in different contexts. As we’ve seen, 1 dwt is equivalent to about 1.55517384 grams, highlighting the difference between these two units.
Is dwt the same as pennyweight?
Yes, dwt is the same as pennyweight. “Dwt” is simply the abbreviation for pennyweight.
This abbreviation is widely used in the jewelry and precious metals industries to denote pennyweight measurements.
How do you calculate pennyweight?
Calculating pennyweight often involves converting from other units of measurement. Here are some common methods:
- From grams to pennyweight:
- Multiply the number of grams by 0.643014931
- From troy ounces to pennyweight:
- Multiply the number of troy ounces by 20 (since 1 troy ounce = 20 dwt)
- From grains to pennyweight:
- Divide the number of grains by 24 (since 1 dwt = 24 grains)
- From carats to pennyweight (for gemstones):
- Multiply the number of carats by 0.8565447885
Grams to Pennyweight Conversion Table

- Small quantities: For small amounts like 0.5 grams, the pennyweight value is less than 1 dwt, which is useful for very precise measurements in jewelry making.
- Common jewelry weights: Many jewelry pieces fall in the range of 1 to 10 grams. The corresponding dwt values (0.64301493 to 6.43014931) are commonly used in the industry.
- Larger quantities: For larger amounts, such as 1000 grams (1 kilogram), the pennyweight value becomes quite large (643.01493100 dwt), which is more relevant in bulk precious metal trading.
- Precision: Note that the conversions are shown to 8 decimal places. In practical applications, the level of precision needed may vary. Jewelers might round to 2 or 3 decimal places, while scientific applications might require greater precision.
