How much weight will 15 ft.³ of helium lift?

How much weight will 15 ft.³ of helium lift?

Mainly curious.

Shucks, I am not a baloonist. But from simple calculatins using
standard density at sea level - 1.22 Kg/CuM and Helium
at 0.179 Kg/CuM - and good old Archimedes I get a boyancy
of about 0.98 lbs. That is probably affected by the
the balloon skin pressure on the helium (makes it shrink),
and other factors. Somebody else double check this???

The http://www.allmeasures.com/ website has a lot of conversions
and density calculations.
