Official Danish krone (DKK) exchange rates from Danmarks Nationalbank, with no key. Get the latest official rate for every quoted currency, a single-currency rate, a currency converter and the list of quoted currencies. The central bank quotes rates as DKK per 100 units, so every rate is also normalised to a per-unit DKK value (rate ÷ 100) and conversions are correct.
