# Centigrams to Pennyweights (cg to dwt) Source: https://www.unitconvertercalculator.com/weight/centigrams-to-pennyweights/ **1 cg = 0.0064301493137256 dwt** One centigram equals approximately 0.006430 pennyweights. The pennyweight (dwt), at about 1.555 grams, is 155.5 times heavier than a centigram. The pennyweight remains the backbone of North American precious metals pricing, while the centigram occupies a rarely visited corner of the metric system. Their intersection occurs mainly in gemological and metallurgical laboratory work. ## Formula Apply the conversion factor ## Conversion Table | Centigrams (cg) | Pennyweights (dwt) | |---|---| | 1 cg | 0.0064301493137256 dwt | | 5 cg | 0.032150746568628 dwt | | 10 cg | 0.064301493137256 dwt | | 50 cg | 0.32150746568628 dwt | | 100 cg | 0.64301493137256 dwt | | 250 cg | 1.6075373284314 dwt | | 500 cg | 3.2150746568628 dwt | | 1000 cg | 6.4301493137256 dwt | | 2500 cg | 16.075373284314 dwt | | 5000 cg | 32.150746568628 dwt | | 10000 cg | 64.301493137256 dwt | | 50000 cg | 321.50746568628 dwt | | 100000 cg | 643.01493137256 dwt | ## Units ### Centigram (cg) A centigram is one hundredth of a gram. It is a metric unit rarely used in everyday life but appears in some scientific and educational contexts. ### Pennyweight (dwt) A pennyweight is a unit of mass equal to 24 grains or 1/20 of a troy ounce (1.55517384 grams). Used in the jewelry trade for weighing precious metals. ## Background American gold dealers quote prices per pennyweight, and a typical gold wedding band weighs 3 to 6 pennyweights (about 467 to 933 centigrams). When a jewelry assay laboratory weighs gold samples on a centigram-resolution balance, the results must be converted to pennyweights for pricing. A centigram of gold at current market prices is worth fractions of a cent, while a pennyweight is worth several dollars. ## Good to Know The pennyweight connects modern American commerce to medieval English coinage through an unbroken chain of usage. When a jeweler in Los Angeles weighs scrap gold in pennyweights, they use a unit that was standardized in England around 1266 under Henry III. Few other units in active daily use can trace their lineage back over 750 years with so little change in definition. ## FAQ ### How many centigrams are in one pennyweight? One pennyweight equals approximately 155.52 centigrams. This comes from 1 dwt being about 1.5552 grams and 1 gram equaling 100 centigrams. ### What is a pennyweight used for? The pennyweight (1/20 troy ounce, about 1.555 g) is used in North America for pricing gold, silver, and other precious metals. Scrap gold is bought and sold by the pennyweight at most US jewelers and refiners. ### Why is the pennyweight abbreviation 'dwt'? The 'd' comes from 'denarius,' the Roman coin the English penny descended from. 'wt' is an abbreviation for 'weight.' So 'dwt' means 'denarius weight' - a linguistic relic of the Roman Empire in modern American jewelry shops. ## Non-Frequently Asked Questions ### If I paid for gold in centigrams, would the dealer be confused? Extremely. Telling a scrap gold dealer you have '933 centigrams of 14-karat gold' when you mean '6 pennyweights' would require explanation, possibly a calculator, and definitely patience. The dealer would convert to pennyweights before quoting a price, because that is the language of the trade. ### Was a pennyweight ever actually the weight of a penny? Originally, yes - it was the weight of a silver English penny in the 13th century. Modern pennies weigh about 2.5 grams (1.6 pennyweights), having long since diverged from their namesake unit. The penny got cheaper; the pennyweight kept its value. ### Is the pennyweight the most American unit that most Americans have never heard of? It ranks highly. Walk into any jewelry store and the owner knows pennyweights intimately. Walk out to the parking lot and ask a random person what a pennyweight is - complete blank stare. It is an intensely specialized trade unit hidden in plain sight on every main street in America. ## Related Articles - [Why We Measure: The Deepest Urge in Human Civilisation](https://www.unitconvertercalculator.com/blog/why-we-measure) - [The Map Is Not the Territory: Why Every Measurement Is Wrong](https://www.unitconvertercalculator.com/blog/the-map-is-not-the-territory) - [Zero: The Most Dangerous Number in Measurement](https://www.unitconvertercalculator.com/blog/zero-the-most-dangerous-number-in-measurement) - [The Kilogram Problem: The Object That Was Its Own Definition](https://www.unitconvertercalculator.com/blog/the-kilogram-problem) - [The Body as a Ruler: Every Measurement Unit That Came From Us](https://www.unitconvertercalculator.com/blog/the-body-as-a-ruler) - [Why Your Recipe Is Lying to You: The Chaos of Cooking Measurements](https://www.unitconvertercalculator.com/blog/why-recipe-measurements-are-unreliable) - [15 Obscure Measurement Units You've Never Heard Of (But Still Need)](https://www.unitconvertercalculator.com/blog/obscure-measurement-units-guide) - [When Measurements Go Wrong - Disasters, Blunders and Happy Accidents](https://www.unitconvertercalculator.com/blog/when-measurements-go-wrong) - [The Surprising Stories Behind Everyday Units of Measurement](https://www.unitconvertercalculator.com/blog/stories-behind-measurement-units) - [Metric vs. Imperial - The Complete Guide to the World's Two Measurement Systems](https://www.unitconvertercalculator.com/blog/metric-vs-imperial-complete-guide) - [Understanding Weight Units - Kilograms, Pounds, Stones & Ounces](https://www.unitconvertercalculator.com/blog/understanding-weight-units) - [Complete Baking Measurement Guide - Cups, Grams, Ounces](https://www.unitconvertercalculator.com/blog/baking-measurement-guide) ## See Also - [Pennyweights to Centigrams](https://www.unitconvertercalculator.com/weight/pennyweights-to-centigrams/)
