Homework Help: Why is the Density of Water almost the same as

  1. Nov 10, 2012 #1
    Why is the density of water almost the same as its weight (in English units)? This isn't really a homework question per se, but it's somewhat germane to what I'm doing right now (hydrostatic pressure and hydrostatic force).

    Or at least part a of the first question on page 5 here seems to suggest so:

    Because you have used the weight density of fresh water, which is approx. 62.5 pounds force per cubic foot. The mass density of fresh water is approx. 62.5 / 32.2 = 1.99 slugs per cubic foot.
