# Amazon.com Roomba WTF - WTF explained in Bold/Italics/Underlined

• If one were to theorize that "dimensions" is measuring the mass of the product and that shipping weight is measuring the weight of the product in its packaging at standard atmospheric pressure and temperature, then we can just assume that the product is shipped in a very large sealed box also containing large quantities of uncompressed helium, or perhaps it is shipped suspended in a vacuum. Since the product is a vacuum, I would like to think of it as the latter.

• Presumably the product dimensions are based upon the size at it's initial point, while shipping weight is what it'll weigh when it gets to you.  Therefore, there are two possible solutions:

1. The package propels itself to you as a rocket, using up almost half its weight as fuel.

2. The package is shipped from a planet with roughly twice the surface gravity of the Earth.

3. The package is shipped via UPS and will lose almost half it's mass in the sorting facilities

• I don't get it...where's the WTF??  Just convert 31.2 lbs to cubic inches.  I don't have a calculator handy or I'd do it.

• the important thing is whether 31.2 lbs fits through your mailbox or not. Since your item is apparently shapeless, I guess they can mold it into a slender, flat entity that fits.

• I was going to convert 31.2 pounds sterling into cubic inches, but I can't find the dimensions online.  Could somebody please mail me some? Thanks.

I'd need the bulk density of the material to do that.... The bulk density of sugar is not equal the bulk density of water, and they will fit different weights in the same container. I'd need the bulk density (lbs/cubic inch) to even try to convert.

• For some reason this thread reminds me of that conversation on Youtube between a man and Verizon (or something), in which the poor man hopelessly tries to make Verizon understand that cents and dollars are not equal to each other.

I just happen to have a measurement calculator here, and it tells me that 31.2 lbs converts to 485.2224 cubic inches.  Seriously.  I have no idea how it determined this.

That wooshing sound you hear is a joke flying well above your head.

• 4.  UPS will empty the dustbag before final delivery.

The Youtube clip on that site doesn't work anymore (either Youtube removed it or consumerist screwed something up on their site).
