Kronor is the money used in Sweden. One is a krona and several are kronor.
The plural catches people out, since krona, kronor and kronen all look similar and belong to different countries. Sweden, Norway, Denmark and Iceland all use a currency with a name meaning crown, and none of them is interchangeable. Sweden has stayed out of the euro and has moved further towards a cashless economy than almost anywhere else, so a great many Swedish shops no longer take kronor in cash at all.
