As of today:
1 SEK = 0.11 Euro -- 1 Euro = 9.23 SEK
1 SEK = $0.12 Dollars -- $1 = 8.26SEK
1 SEK = £0.077 -- £1 = 12.95 SEK
Be careful if you do go as the Norwegian Currency (Krone - NOK) and the Danish Currency (Krone - DKK) sound very similar and, depending on where you go, they may not accept the currency if it's wrong. As an example, waiting in line at a sandwich shop at Copenhagen Airport and the guy infront of me couldn't use his Swedish Krona.
Hope this helps.
To add onto what the other said. It is probably rude to try to give your Swedish kroner to the Danes or other shopkeepers in Scandinavia. I know it is offensive to assume that we will accept American money here in Canada.
It's offensive in Canada because too many people assume US dollar rules supreme. In Scandinavia, hardly anyone will make such assumptions apart from the most uninformed tourists
When I was at Copenhagen Airport, I could pay with SEK everywhere. I guess especially at airports, they should take all kind of currencies, since there are a lot people form everywhere on the world.
Please note we're in the process of getting new banknotes. Some of the banknotes on that picture are no longer valid, and some are valid now but won't be a year from now. See this page for which ones are valid today: http://www.riksbank.se/en/Notes--coins/Banknotes/Valid-banknotes/
If it is a Norwegian one, since it has a little hole you can use it as a washer. ;)
Is it wrong to translate as "Do you have one kronor". I thought "a" or "one" would both be correct.
