How many g of protein for maintenance/gain

What is the exact conversion for amount in g of protein you have to eat every day just for maintenance, and the one for growth? There used to be a great excel chart posted on here about that but I cannot find it. Does anybody know off hand I have heard everything form 1.8 - 2.5 g per kg of weight

Thanks bros

It's at least 1g/ lbs of body weight. So telling that it would be at least 2.2mg/Kg.

the more the better especially while on steroids!
