The Swedish Monetary Unit is commonly referred to as the Krona or SEK. Sweden's currency has been the Krona since 1873, following a monetary reform where the Riksdaler was replaced. The word Krona means "crown" in Swedish, and its symbol is a "kr." The Krona is subdivided into 100 öre, but as of 2010, no coins or banknotes denominated in öre are used anymore. The word "Krona" is the most common synonym for the Swedish Monetary Unit, but some other words that are often used include the Swedish Crown, the Swedish Krone, and the Swedish Currency.
