What does fyi ac mean?

"FYI AC" is not a common or standard abbreviation. It's possible it's a specific acronym used within a particular organization or context.

Here's why it's confusing and what you can do:

* "FYI" is already an abbreviation: It stands for "For Your Information," so adding "AC" after it is redundant.

* "AC" has many meanings: It could stand for "Air Conditioning," "Alternating Current," "Account," or "After Christ," among other things.

To understand what "FYI AC" means, you need more context:

* Where did you see it? Was it in an email, a text message, a website, or a document?

* What was the topic of the message? This can give clues about the meaning of "AC."

If you can provide more context, I can help you figure out what "FYI AC" stands for.
