really?
because I learned to write it as とう, not とお
for whatever reason, we were taught to use the う in hiragana, and the straight line in katakana, even though you usually write it as "u" in roomaji
There are exceptions to pretty much all rules; this is one such case. In general, for an extended "o" sound, you will use -おう, but in the case of the Japanese number system's 10, you write とお. It's simply an exception, and you need to learn them as you go. This is why it's not good to learn Japanese using Romaji.
As for Katakana, though, you are correct in that you use the line: コーヒー (koohii or coffee).
I don't learn through roomaji, that's just how I was taught
even though it's an "o" sound, always use the "u" character (in hiragana, for extended o-vowels)
thanks for the info!

EDIT:
oh, and this part "even though you usually write it as "u" in roomaji"
should have said "even though you usually write it as "o" in roomaji"
