The krona (Swedish: [²kruːna]; plural: kronor; sign: kr; code: SEK) has been the currency of Sweden since 1873. Both the ISO code "SEK" and currency sign "kr" are in common use; the former precedes or follows the value, the latter usually follows it but, especially in the past, it sometimes preceded the value. In English, the currency is sometimes referred to as the Swedish crown, as krona literally means crown in Swedish. The Swedish krona was the ninth-most traded currency in the world by value in April 2016.One krona is subdivided into 100 öre (singular and plural; when referring to the currency unit itself, however, the de facto plural form is ören). However, all öre coins have been discontinued as of 30 September 2010. Goods can still be priced in öre, but all sums are rounded to the nearest krona when paying with cash.
