The Kracken:
A liter equals a kilogram ? ? ? ?

If I fill a 1 liter bottle full of lead shot, I'll bet you a pile of pig poop to a pile of doubloons that it'll weigh more than 1 kilogram.

Don't confuse volume with weight.

Easy, there..
Let's not release the Kracken...

One liter of pure water weights one kilogram, which is one of the things that makes the metric system so darn convenient.

A kilogram weighs like 2.2 pounds, so the wing that is 40 liters would have like 88 pounds of lift.

I guess it's safe to say it has enough lift...

The OMS bladders are what many of those who believe bungies are a problem point to as an example. They're a problem (if I remember right) not because of any particular entanglement hazard, but because the bungies can squeeze the air out of the wing in the event of a failure... making a bad situation much worse much more quickly.

If you dont know the reason why comment on it, you are just furthering the myth, please stick to the facts you know.

The OMS wing with retractors is normally set so that the retractors limit how far the wing can expand. In the event of a leak in the wing they DO NOT squeeze all the air out, this is just bollox. I dont have one of these wings i think they look messy and probably are a potential entanglement hazard, but i have taken the time to look at one and how it works, rather than spouting misheard rubbish that someone else has come up with.

If i had a dollar for every time someone on SB has made this statement about OMS bungies i would be able to afford one myself ;)

The bungee rhetoric has taken me to edge of getting banned from this sight in the past. I dive with OMS gear, but not the bungeed wings. People think the bungees, when retracted, don't allow for any air in the bladder. Hogwash. A leak in a bladder at depth doesn't need bungees to do the job when water pressure will create the same effect. All the bungees do is keep the excess material on large wings pulled in when not inflated. Now that being said, Dive Rite has semi-bungeed wings as well. They do the same thing the OMS bungees do, but are only on the front side of the wing. They eliminate the problem that I see with the OMS wing - entanglement. So, are bungeed wings bad? For environments with entanglement potential - YES. For non-entaglement environments - NO. I wouldn't buy a bungeed wing because I do both environments and don't really feel there is a need for bungees in the first place. But I agree that people just spit out what they have heard without doing any research on the matter.

I do agree, that if one wants to go with a simple setup - the bp and wing is the way to go. If you want all the pockets and cumberbunds and such, then go with a back inflation bc or trans pac setup.

Is this context, yes a liter equals a kilogram. The question was how to convert liters of blader volume into pounds of float. So what matters is the weight of water displaced by a liter of air. For this purpose it close enough to just
multiply liters by two and get pounds of lift. To get an _exact_ figure you
need to work harder. and take into concideration that sea water is more dense
than fresh and the weight of the BC is sea water and other details like to exact number of oz per liter

But to answer the question "does a 40 liter BC provide a lot of float?" a simple
conversion to 80 pounds answers the question well enough, yes 80 pounds is a lot
for a single tank rec. diver.
