Meaning of ac?

[goodstudent]

So am I right to say that all English speaking countries understand "ac" as short for "account"?

No. For a start, read post #8 again.

When in doubt, goodstudent, write the word out in full; you don't need to spend several minutes pondering how to save one second — the time it takes to make the few extra keystrokes.

I was going to write short form inside excel. The width space is limited, so I thought if I could shorten the account word to short form.

In the accounting books, a/c means account. Double-entry bookkeeping system - Wikipedia, the free encyclopedia
So actually my question is about whether a/c or ac is short form for account in all circumstances.
Since everyone here agree with post 8, I would just take it that a/c is only used in accounting books. a/c or ac is not commonly used in English language as short form for account

Have you read all the posts? And why do you think that everyone agrees with post #8? It's not a case of agreeing with it or not. Post #8 only said that it would not be used as an abbreviation for "account" in AmE. I clearly said that in BrE, it's used a lot, not just in accounting books. If you are looking for an abbreviation that is in normal usage in all English-speaking countries, I don't think you'll find one.
