What you need to know about Norwegian currency
If you're wondering what's Norway's currency the answer is not Euros. Actually, Norway still hasn't joined the euro area, having its own national currency, called the Norwegian krone.
Historically, many of the national European currencies are called 'krona' due to the king's crown, illustrated on the coin. Currently, there exists the circulation of banknotes of 50, 100, 200, 500 and 1000 krones in the NOK currency as well as coins of 20, 10, 5, and 1 krone.
The easiest and safest way to exchange the Norwegian krone to USD and vice versa is to go to one of the many official currency exchange offices or to a local bank. Also, to help you understand the ratio and convert NOK to USD, 10 krones is approximately 1.25 US dollars.
