How do i determine how much weight i need

Question

It's been a number of years and a few extra pounds since I last dove.  I don't remember how much weight I last used.  Is there a way to figure this out before i go diving next? (I plan to wear a 3mm wetsuit)

Thanks

Adam

Try working with the following table as suggested from PADI.
 

Exposure Suit Type	Start With
Swimsuit/dive skin	1 - 4 lbs
3 mm/1/16 in. one piece wet suit, shorties, jump suit	5% of your body weight
5 mm/3/16 in. two piece wet suit	10% of your body weight
7 mm/1/4 in. wet suit w/hood & gloves	10% of your body weight, + 3 - 5 lbs
Neoprene dry suit	10% of your body weight, + 7 - 10 lbs
Shell dry suit, light undergarment	10% of your body weight, + 3 - 5 lbs
Shell dry suit, heavy undergarment	10% of your body weight, + 7-14 lbs
Salt/Fresh Water change
Body Weight	Add(going to salt) or subtract (going to fresh)
100 - 125 lbs	4 lbs
126 - 155 lbs	5 lbs
156 - 186 lbs	6 lbs
187 - 217 lbs	7 lbs
