Air is about 1/800 the density of water, and water is 62.5 pounds per cubic foot, or 0.016 cubic feet per pound; that makes air about 12.8 cubic feet per pound.

If the material being stored is above a certain density, weight (mass) is the limit. Below that density, volume is the limit. Different items (material) have different densities.

Re: [Magic] A Pound Takes Up 2 Cubic FEET?!
So what material has a density of less than 0.01 of water where we should worry about volume more than weight?

It's often useful to have a capacity in terms of volume as well as weight. |

A 40-foot ladder that can't be collapsed?
A cloud of toxic gas? A 2-foot-wide hollow glass sphere? Aerogel? Feathers? An extremely large and fragile magical origami?

Re: [Magic] A Pound Takes Up 2 Cubic FEET?!
Exactly. While it won't come up often in a DF/regular Fantasy game, I've had it come up a few times in a Technomancer game... the aforementioned "smuggling helium"... granted it was magical helium, which made it worth it, but the PCs were far more worried about volume than weight on the Hideaway air tanks.

LOL. The idea that magic isn't involved and changing things in some way.

Additionally I'm pretty sure that helium is normally stored for transport under pressure and for magically-enhanced helium I see no reason why removing this property would be beneficial. So what your PC's should have done is had their pockets enchanted with Hideaway and had the mouths of the inter-dimensional pocket fitted with helium proof tanking apparatus and simply carried the stuff out in their pockets! |
