Non-Frequently Asked Questions About Drams to Troy Ounces

Questions nobody should ask - but someone did.

A medieval spice merchant knew drams, ounces, and pounds. The Feinunze 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.
A merchant who bought spices in drams and sold the proceeds to buy gold in troy ounces might have needed this conversion. But in practice, spice merchants and goldsmiths were different people at different stalls. They shared a currency but not a measurement system.
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.
