A neologism for “kilometer” in the Neo-Quenya Wiki, a direct borrowing of the European word since it fits Quenya phonology. The Neo-Quenya Wiki also had ᴺQ. húmeter using the Quenya word ᴺQ. húmë for “hundred”, but I am of the opinion that if you are going to borrow part, you may as well borrow all, since this is the general practice for the metric system.
