[edit] Metric conversion of apothecaries' weights
The list is not complete; e.g. the metric equivalents of a pound within the Kingdom of Piedmont-Sardinia or the Duchy of Parma could vary by up to 8% and have been omitted for simplicity.[1]
Nürnberger Medicinalgewicht (Pondus med. Noricum): 1 Libra = 357.8436 g.
As of 1835, this was used in:
Badische Verordnung vom 10. Februar 1854: Apothekerpfund = 375 g as in Belgium, rather than 357.78 g as before. (Norwegisches Medicinalpfund = 357.8452 g.) [3]

English Troy weight system
The Tower pound seems to have been something more than the Roman pound, and something less than the Troyes pound. This last was not introduced into the mint of England till the 18th of Henry the VIII. The French livre contained, in the time of Charlemagne, a pound, Troyes weight, of silver of a known fineness. The fair of Troyes in Champaign was at that time frequented by all the nations of Europe, and the weights and measures of so famous a market were generally known and esteemed. The Scots money pound contained, from the time of Alexander the First to that of Robert Bruce, a pound of silver of the same weight and fineness with the English pound sterling. —Adam Smith, The Wealth of Nations
