Wikipedia says "The saying "a

English-speaking world, an Imperial pint-being 20 Imperial ounces of
water-will weigh one and a quarter pounds."
Exactly the rule of thumb I learned it as a kid. ?To this day, it has
told me that a 250 gallon tank filled with water sitting in the back
of my pickup weighs about a ton, plus whatever the (PVC) tank weighs.
A little 50 gallon water-filled tank weighs more than 400 lbs.
...another rule of "thumb" is that the distance from the tip of your
thumb to the knuckle is about an inch. ?In my case, it's more
accurate than "three barleycorns, dry and round" from my pantry,
which measured only about 3/4 of an inch.
How anyone can love Imperial measurements is beyond me. I am 42 and
grew up with the tail-end of them and I hate them with a burning
passion. Give me metric any day, where 1 litre in the USA is the same
as 1 litre anywhere and 1 litre of water masses 1kg anywhere on the
planet or indeed off it (at least unless it is travelling very quickly
indeed).
