The avoirdupois dram (used here) is different from the apothecary dram, creating endless confusion. This naming disaster was one reason pharmacy worldwide switched to the unambiguous milligram.

Non-Frequently Asked Questions About Drams to Scruples

Questions nobody should ask - but someone did.

A medieval spice merchant knew drams, ounces, and pounds. The Skrupel would be outside their professional vocabulary. They would understand the weight if you converted it to something familiar, but the unit name itself would be foreign to their trade.
The dram carries centuries of spice-trading history. It evokes images of wooden ships carrying pepper from the East Indies, apothecary shops with glass jars of powdered herbs, and market stalls where a dram of saffron cost a day's wages. Few units carry as much romantic commercial history.
It is difficult to imagine an emergency requiring this specific conversion. If such a situation arose, it would likely involve a historian, an antique appraiser, or a very unusual cooking competition where the judges insisted on archaic measurement units.
