Is a dram the same as a drachm?

The drachm is the British spelling of the same unit when referring to the apothecary dram. However, the avoirdupois dram (used in everyday commerce) and the apothecary drachm (used in pharmacy) have different weights. The avoirdupois dram is about 1.772 grams, while the apothecary drachm is about 3.888 grams.

Why are there different types of drams?

Historical measurement systems developed independently for different purposes. The avoirdupois system served general trade, while the apothecary system served medicine. Both used the word 'dram' for a small weight, but defined it differently. This kind of naming collision was common before international standardization.

The word 'dram' descends from the Greek 'drachma,' an ancient coin that also served as a unit of weight. In the 19th century, American shotgun shells were marketed by their 'dram equivalent' - a measure of muzzle velocity benchmarked against black powder charges measured in drams. Even after smokeless powder replaced black powder, the dram equivalent label persisted on ammunition boxes until recent decades.

Non-Frequently Asked Questions About Hectograms to Drams

Questions nobody should ask - but someone did.

Only etymologically. A 'dram' of whisky is an informal Scottish measure meaning a small pour - typically around 35 to 50 milliliters. It has no fixed relationship to the weight unit. Ordering a dram at a pub and receiving 1.772 grams of liquid would be both disappointing and confusing.
Your doctor would almost certainly pause, possibly check whether you had suffered a head injury, and then convert it to about 56 hectograms or 5.6 kilograms - which would mean you are either a very small cat or something went very wrong with the scale. The unit is simply not used for body weight anywhere.
Because the avoirdupois system was never designed with metric compatibility in mind. The dram equals exactly 27.34375 grains, and one grain equals exactly 0.06479891 grams - a value that was itself derived from matching historical standards. Layer upon layer of non-decimal conversions produce these wonderfully ugly decimals.
