Pot odds question

[cmillard]

I need some help with applying odds.....I understand counting my outs and coming up with a % chance of hitting.

What I am having trouble with is comparing that % with the pot size and/or a bet that is made to the pot.

How do I know what % chance is okay to make a call? When I hear the phrases like "4 to 1 on my money to call", I don't really understand what I am looking for.

I hope what I am asking makes sense.

Thanks for any help.
