Currency Units
ISO currency codes (EUR, NOK, USD etc.) are recommended (see Appendix B). These are to be written before the numerical value (example: EUR 15 million). ISO currency codes are best in written English but in oral presentations it is more natural to refer to NOK as krone (never "N,O,K" or "crown"), USD as dollar or US dollar and EUR as euro. (Note euro is not capitalized and the plural is euro.)

 
The currency code is always written first but never read first in English.

Spoken English

Two million Norwegian kroner

Fifty-five euro fifty (cents)

Twenty-five US dollars fifty (cents)

Three pounds (Sterling) twenty (pence)

Do not abbreviate billion as bill. or million as mill. In the latter case there may be confusion with milliard or the French mille.

The use of "K" for "kilo" and "M" for "million" before an ISO currency code (such as KEUR and MUSD) may be confusing. Write USD 25 billion, not KUSD 25 million; NOK 25 million, not MNOK 25. Similarly an amount such as

EUR 25 000, should not be written EUR 25k or EUR 25K.
