There's no formula for the weight of a cubic foot of water, any more than there's a

formula to calculate the weight of your best friend. You just have to weigh them, or

look it up in a book, and then you know.

In the case of a cubic foot of water, it's pretty easy, because if the water is pure

and the temperature and pressure are the same every time, then every cubic foot

has the same weight.

" 621/2 pounds " is an easy number to remember, and it's quite close.
