Franc

The franc (₣) is the name of several currency units, most notably the Swiss franc, still a major world currency today due to the prominence of Swiss financial institutions and the former currency of France, the French franc until the euro was adopted in 1999 (by law, 2002 de facto). The name is said to derive from the Latin inscription francorum rex ("King of the Franks") on early French coins, or from the French franc, meaning "free" (and "frank").

The countries that use francs include Switzerland, Liechtenstein, and most of the Francophone countries of Africa. Before the introduction of the euro, francs were also used in France, Belgium and Luxembourg, while Andorra and Monaco accepted the French franc as legal tender (Monegasque franc). The franc was also used within the French Empire's colonies, including Algeria and Cambodia. The franc is sometimes italianised or hispanicised as the franco, for instance in Luccan franco.

One franc is typically divided into 100 centimes. The French franc symbol was an F with a line through it (₣) or, more frequently, only an F.
