You may recall that I posted a web address here a few days ago that showed Thomas Jefferson's thoughts on reforming the measuring methods for the USA.
Why I am posting this again is simply to alert you to Jefferson's thoughts on 1000 ounces and cubic feet. Go to:

Came across this while looking up Avoirdupois ounces.

The Weight of a cubic foot of pure water, is 1000 ounces, or 62 1/2 pounds, avoirdupois. And the Weights of the cubic foot of other bodies, are as set down under the article Specific Gravity.
This might have been the case at some point, but changed when they changed the inch definition. 62,5 lbs is 28,35 kg. A cubic foot is 28317 cm3 or 28,317 kg. Interesting correlation nonetheless.
