I had a discussion with a friend last night of just how big a cubic box containing 100 lbs of human fat would need to be. I’m assuming human fat and water have approximately the same density (I know it’s not perfect but IIRC it’'s very close). I could do the conversion factoring (ie 1cc = 1 gram of weight) but it’s late and I’m tired. Does anyone have a direct conversion factor for lbs of water to cubic feet of volume?
62.5 lbs per cubic foot but fat is lighter than water.
A cubic foot of water weighs about 62.5 lb. Fat is about 10 or 20 percent less dense than water. Human adipose tissue consists of fat, water, and other stuff and has a denisty somewhere around 60 lb/ft[sup]3[/sup]
In rough numbers:
1 gal. of water = 8.3 lbs
1 gal. = 231 in[sup]3[/sup]
Therefore,
100 lbs water = 12 gal. = 2770 in[sup]3[/sup], or about 14 inches on each side.
Or:
100 lbs equals 45359.237 grams, or cubic centimeters of water.
The cube root of 45359.237 cubic centimeters is
35.6633317 centimeters or
About 14.040682 inches.

But fat floats.
Thanks!
This would be soooo much easier if it were METRIC!!!
A pint’s a pound, whole world 'round.
You can convert to metric here and then report the answer back without showing your work, and look so smart.

Rule of Reason: “If nobody uses it, there’s a reason.”
And a pint is 1.043176 pounds, in the US, but in UK it is 1.252802 pounds.

You know, when you calculate your response to six decimal places, you don’t need to preface the answer with ‘about’.
