# Hundredweights (US) to Grains (cwt to gr) Source: https://www.unitconvertercalculator.com/weight/short-hundredweights-to-grains/ **1 cwt = 700000 gr** One short hundredweight equals exactly 700,000 grains. This impressively round number comes from the defining relationship of 7,000 grains per pound multiplied by 100 pounds per hundredweight. The grain, as the smallest and most fundamental unit in the avoirdupois system, subdivides the hundredweight into seven hundred thousand identical pieces. ## Formula Apply the conversion factor ## Conversion Table | Hundredweights (US) (cwt) | Grains (gr) | |---|---| | 0.001 cwt | 700 gr | | 0.005 cwt | 3500 gr | | 0.01 cwt | 7000 gr | | 0.05 cwt | 35000 gr | | 0.1 cwt | 70000 gr | | 0.5 cwt | 350000 gr | | 1 cwt | 700000 gr | | 2 cwt | 1400000 gr | | 5 cwt | 3500000 gr | | 10 cwt | 7000000 gr | | 50 cwt | 35000000 gr | | 100 cwt | 70000000 gr | ## Units ### Hundredweight (US) (cwt) A US hundredweight (short hundredweight or cental) is exactly 100 pounds or 45.359237 kilograms. Used in US agriculture and commodities trading. ### Grain (gr) A grain is a unit of mass equal to exactly 64.79891 milligrams. It is the same in the avoirdupois, troy, and apothecaries' systems, derived from the 1959 international agreement defining the pound as exactly 0.45359237 kilograms. ## Background Ammunition reloaders purchasing powder by the hundredweight and measuring charges in grains work across this conversion regularly. A hundredweight of smokeless powder contains enough grains for tens of thousands of individual cartridge charges. The clean 700,000-grain ratio makes inventory calculations straightforward. ## Good to Know The 700,000-grain hundredweight is the imperial system at its most elegantly simple. Two round numbers (7,000 and 100) multiply to produce a third round number (700,000), creating a chain of clean arithmetic from the smallest unit (grain) to a substantial bulk measurement (hundredweight). This mathematical beauty is often lost in criticisms of the imperial system, which focus on its cross-system conversions rather than its internal consistency. ## FAQ ### How many grains are in one short hundredweight? One short hundredweight contains exactly 700,000 grains. This is 7,000 grains per pound times 100 pounds per hundredweight. ### Why is this number so clean? Because both factors are clean numbers: 7,000 grains per pound (a defining constant of the avoirdupois system) and 100 pounds per hundredweight (the defining feature of the American short hundredweight). Their product, 700,000, inherits cleanliness from both parents. ### How do I convert short hundredweights to grains? Multiply hundredweights by 700,000. For example, 0.1 hundredweights (10 pounds) equals exactly 70,000 grains. ## Non-Frequently Asked Questions ### Is 700,000 the roundest number in weight conversion? It is certainly one of the roundest large numbers. Most inter-unit conversions produce ugly decimals, but 700,000 grains per hundredweight is clean, exact, and divisible by an impressive variety of numbers. It reflects the rare alignment of two independently defined round numbers (7,000 and 100) multiplied together. ### How many rifle cartridges could I reload from a hundredweight of powder? A typical rifle charge is 40 to 60 grains of powder. At 50 grains per charge, 700,000 grains would load 14,000 cartridges. That is enough ammunition for several years of regular target shooting or hunting, and more than any individual needs to have on hand at once. ### If each of the 700,000 grains were a grain of rice, how many meals would that be? A single serving of rice contains roughly 3,000 to 4,000 grains of actual rice. So 700,000 rice grains would make about 175 to 233 servings, or roughly 6 to 8 months of daily rice consumption for one person. Confusingly, 700,000 grains of weight and 700,000 grains of rice are not the same mass, since the weight grain (65 mg) and a rice grain (25-30 mg) differ by a factor of about 2. ## 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 - [Grains to Hundredweights (US)](https://www.unitconvertercalculator.com/weight/grains-to-short-hundredweights/)
