So, what’s smaller than a Euro and how many of them equal 1 Euro?
There are 100 cents in 1 euro.
ETA: In full, the unit is called a “euro cent”.
For the love of all things holy, don’t encourage non-Brits to say ‘quids’.
Except that according to EU legislation (cited in pulykamell’s post) and the coins themselves, there are 100 cent in one euro.
I lived in Italy and Germany. To me, it seemed like Germans would sat Euro and Italians would say Euros. I always use the singular.
To add, I can tell you both of Thailand’s English-language dailies, The Nation and the Bangkok Post, which generally use British style, use “euros” for the plural.
For a long time, the Post did not even use the euro sign due to a programming glitch screwing up the symbol on the Web edition, but that’s since been fixed. So they in particular used “10 euros” etc.
On my collection of euro cent coins, the term used is “EURO CENT”, with “EURO” in smaller letters than “CENT”.
That’s exactly what’s on the euro coin(s).
I’ve always thought it was “Euros” with a pronunciation similar to saying “your rose” literally as fast as you can.
I’ve never lived there though, so I’d be happy to learn the correct way to say and pronounce it.
'jʊə rəʊ
Damn! Out-pedanted!
Bless you!
Would you like a tissue? 
In English that is exactly how you would say it.
yes, please. 
'jʊə rəʊ
From the phonetic alphabet.
The apostrophe signals the accented syllable.
Then the “j” is pronounced like the “y” in “yes”
The “ʊ” like the “oo” in look
The “ə” like the “a” in “again”
The “r” like a normal “r” in the word “read”
The “əʊ” like the “o” in the word “go”
YMMV
