Non-Frequently Asked Questions About Hundredweights (US) to Drams

Questions nobody should ask - but someone did.

Nearly. 25,600 = 100 x 256 = 100 x 2⁸. The 256 factor comes from the two successive 16-fold divisions (16 x 16 = 256), which are pure powers of 2. The factor of 100 comes from the hundredweight's definition. So 25,600 is the product of a decimal round number and a binary perfect power, making it a hybrid of two counting philosophies.
A typical cup of coffee uses about 10 grams or 5.6 drams of ground coffee. To brew a hundredweight (25,600 drams) of liquid coffee, you would need significantly fewer drams of grounds since water provides most of the weight. But if you tried to make coffee from 25,600 drams of grounds, you would produce approximately 4,571 cups, enough for a medium-sized office for about three months.
The dram is certainly underappreciated. Everyone knows ounces, most people know pounds, but the 16-dram ounce is a mystery to the general public. The dram survives mainly through shotgun shell labeling and the occasional cocktail recipe, making it the imperial system's most niche surviving subdivision of the pound.
