# Centigrams to Drams (cg to dr) Source: https://www.unitconvertercalculator.com/weight/centigrams-to-drams/ **1 cg = 0.0056438339119329 dr** One centigram equals approximately 0.005644 drams (avoirdupois). The dram, at about 1.7718 grams, is roughly 177 times heavier than a centigram. This conversion bridges a barely-used metric unit with a nearly-obsolete imperial one, connecting the systematic decimal world of the metric system to the medieval English trading tradition. ## Formula Apply the conversion factor ## Conversion Table | Centigrams (cg) | Drams (dr) | |---|---| | 1 cg | 0.0056438339119329 dr | | 5 cg | 0.028219169559664 dr | | 10 cg | 0.056438339119329 dr | | 50 cg | 0.28219169559664 dr | | 100 cg | 0.56438339119329 dr | | 250 cg | 1.4109584779832 dr | | 500 cg | 2.8219169559664 dr | | 1000 cg | 5.6438339119329 dr | | 2500 cg | 14.109584779832 dr | | 5000 cg | 28.219169559664 dr | | 10000 cg | 56.438339119329 dr | | 50000 cg | 282.19169559664 dr | | 100000 cg | 564.38339119329 dr | ## 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. ### Dram (dr) A dram (avoirdupois) is a unit of mass equal to 1/16 of an ounce or 1/256 of a pound (1.7718451953125 grams). Historically used in pharmacy and old cooking recipes. ## Background The avoirdupois dram was once a standard unit in British and American apothecary and spice trades. A centigram, at just 10 milligrams, measures quantities typical in laboratory analytical work. Converting between them might arise when interpreting historical British pharmaceutical formulas that used drams alongside a modern laboratory balance reading in centigrams. A typical dram of ground pepper (about 1.77 grams) equals roughly 177 centigrams. ## Good to Know The dram's name traveled from ancient Greece (drachma) through Rome and medieval Europe to reach English-speaking markets. Along the way it accumulated different definitions in different systems - the avoirdupois dram, the apothecary dram, and the fluid dram. The centigram, by contrast, was born fully defined from the clean logic of the metric system. Their meeting in a conversion table represents the collision of organic, centuries-old measurement evolution with deliberate, rationalist design. ## FAQ ### How many centigrams are in one dram? One avoirdupois dram contains approximately 177.18 centigrams. This comes from 1 dram equaling about 1.7718 grams, and each gram containing 100 centigrams. ### What is the avoirdupois dram? The avoirdupois dram is 1/16 of an avoirdupois ounce, equal to about 1.772 grams. It should not be confused with the apothecary dram (about 3.888 grams), which is a different unit with the same name. ### Is this conversion ever used in practice? Rarely. Both the centigram and the avoirdupois dram are uncommon in modern measurement. This conversion is most likely to arise when digitizing historical recipes or pharmaceutical records that used drams and converting them for modern metric laboratory use. ## Non-Frequently Asked Questions ### If two nearly-extinct units convert into each other, does anyone notice? This conversion is like two rare birds meeting on a deserted island - technically significant but witnessed by almost no one. The centigram clings to life on a few old European scales, and the dram survives in a handful of American spice references. Their meeting point of 0.005644 is known mainly to conversion table completionists. ### Could a medieval spice merchant understand centigrams? The concept of 'one hundredth of a gram' would have baffled a medieval merchant, since the gram was not invented until 1795. They understood drams, scruples, and grains. A centigram is about 0.154 grains - a quantity so small that medieval scales could not have detected it. The merchant would have dismissed centigrams as impractically tiny. ### Is there a sadder pair of units than centigrams and drams? Both units had their moments of glory. The dram ruled spice cabinets and apothecary shops for centuries. The centigram had brief relevance on 19th-century laboratory balances. Now they share the fate of obsolescence, united mainly by conversion tables that connect the forgotten corners of two measurement systems. ## 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 - [Drams to Centigrams](https://www.unitconvertercalculator.com/weight/drams-to-centigrams/)
