BB30 Chainset weights

Looking for a new BB30 chainset and wanting to know if when they give weights it includes the bottom bracket.
eg SRAM Force says 645g w/bb. Does the 'w' mean with or without?
FSA SL-K Carbon chainset website shows figures under 'Crankweight' which I'm guessing excludes the bottom bracket element especially as it's under the 600g mark.
Cheers
Steve

Most BB30 stated crank weights will be without BB. The BB is only two 6806 size bearings, circlips, a couple of dust caps and some shims. A typical BB30 BB will weigh 65-70 grams and are sold separately from the cranks.

Thanks for that.
So if I have an existing FSA Gossamer Pro BB30 chainset and upgrade to a SRAM Force or FSA SL-K Carbon I can simply retain the existing BB bearings in the frame or do I have to buy SRAM/FSA specific bearings?
First BB30 bike I've had you see.
Cheers for your help guys.

Depends on if the spacers/dust caps comes with the crankset or the BB. They might also be integrated into the crankarms, I know they are on some FSA cranksets. Yes you can use the same bearings.
