The Mark (from Middle High German: Marc, march, brand) is originally a medieval weight or mass unit, which supplanted the pound weight as a precious metals and coinage weight from the 11th century. The Mark is traditionally a half pound weight[citation needed] and was usually divided into 8 ounces or 16 lots.[citation needed] The Cologne mark corresponded to about 234 grams.[citation needed]

Like the German systems, the French poids de marc weight system considered one "Marc" equal to half a pound (8 ounces).[citation needed]

Just as the pound of 12 troy ounces (373 g) lent its name to the pound unit of currency, the mark lent its name to the mark unit of currency.
