Gram to Pennyweight – How to convert g to dwt
Whether you're dealing with precious metals or small-weight measurements, understanding how to convert Gram to Pennyweight (g to dwt) is essential for accuracy. This guide explains everything from definitions and formulas to quirky facts and historical usage, so you can convert confidently and correctly.
What is a Gramb and a Pennyweight?
-
The gram (g) is a fundamental unit of mass in the metric system, used globally in science, industry, and everyday tasks. Defined as 1/1000 of a kilogram, it's perfect for small weights — from medicine doses to jewelry components. Introduced during the French Revolution in 1795, the gram was part of a broader movement toward standardized, rational systems of measurement.

The pennyweight (dwt) is a traditional unit from the troy weight system, historically used to weigh precious metals like gold and silver. It equals 24 grains or about 1.55517384 grams. While lesser known outside of niche industries, it remains highly relevant in jewelry, dentistry, and metal trading.
The name "pennyweight" comes from medieval England, where it referred to the weight of a silver penny. To this day, it's used in jewelry stores, pawnshops, and bullion trading across the U.S. and U.K.

The gram was initially defined by the weight of a cubic centimeter of water at 4°C, the temperature at which water reaches its maximum density. This standard was central to the Enlightenment-era push for scientific precision during the French Revolution.
-
In the series Breaking Bad, Jesse Pinkman refers to using a pennyweight to measure gold dust. While dramatized, the unit is a real and commonly used standard in jewelry and metallurgy, especially in the U.S.
-
In 1960, the International System of Units (SI) officially defined the gram via a physical platinum-iridium kilogram stored in France. This was replaced in 2019 by a definition based on Planck’s constant, using quantum physics to ensure universal accuracy.

Many jeweler's scales sold in the U.S. come pre-set with “dwt” as the default display mode. This highlights the unit’s ongoing relevance in specialized trades like goldsmithing, despite the global dominance of the metric system.
When a Coin Defined a Kingdom
In medieval England, the silver penny wasn’t just a coin — it was the basis for an entire measurement system. Minted during the reign of King Offa in the 8th century, the coin weighed roughly one pennyweight. This simple standard helped shape the troy weight system, which went on to define how precious metals are weighed even today. Over centuries, as empires expanded and economies evolved, this little coin left a massive legacy — from royal mints to modern digital scales in jewelry shops.
Conclusion
From ancient coins to quantum standards, converting Gram to Pennyweight (g to dwt) connects the worlds of science, trade, and tradition.
