List of Countries Using Type K Electric Plug & Socket:
Bangladesh, Denmark, Faeroe Islands, Greenland, Guinea, Madagascar, Maldives, St. Vincent, Senegal, Tunisia.

The Danish standard is described in Afsnit 107-2-D1. The plug is similar to F except that it has a grounding pin instead of grounding clips. A type C plug fits perfectly into a type K socket. The Danish socket will also accept either the CEE 7/4 or CEE 7/7 plugs: however, there is no grounding connection with these plugs because a male ground pin is required on the plug. Because of the huge amount of E/F plugs in Denmark, the Danish government decided to make it legal to install type E instead of type K sockets from 2008 onwards.
