The koruna (sign: Kč; code: CZK) is the currency of the Czech Republic since 1993, and in English it is sometimes referred to as Czech crown. The koruna is one of European Union's 11 currencies, and the Czech Republic is legally bound to adopt the euro currency in the future.
The official name in Czech is koruna česká (plural koruny české, though the zero-grade genitive plural form korun českých is used on banknotes and coins of value 5 Kč or higher). The ISO 4217 code is CZK and the local acronym is Kč, which is placed after the numeric value (e.g., "50 Kč"). One koruna equals 100 haléřů (abbreviated as "h", singular: haléř, nominative plural: haléře, genitive plural: haléřů - used with numbers higher or equal to 5 - e.g. 3 haléře, 8 haléřů).
