Weight for use when gluing

[John Stankus]

Surely a gallon of water weighs 10lbs.

"A pint of pure water weighs a pound and a quarter".

Depending on the temperature the weight of a gallon of pure liquid water at atmospheric pressure varies from about 8.34 lbs/gal near the freezing point down to just under 8 lbs/gal just below the boiling point.

Reminds me of an interesting point; the gas pumps in Canada are temperature compensated, the gas pumps in the US are not. If you have an uncompensated pump and the temperature is lower than standard it favors the consumer, if the temperature is higher it favors the seller. (it's one of those things that make you want to go hmmmm!?! with apologies to Arsenio)

I have a couple of 8" Diameter "cores", 12" long, from a concrete wall at one of my jobsites years ago. I used to put one behind each wheel, in the trunk of my daughter's car in the winter for a little extra weight.

John, I was being playful.

Not all gallons are created equal.

A U.S. gallon is 3.785 litres, an Imperial gallon is 4.546 litres and was infact, if memory serves, once defined as 10lbs of freshwater at 62°f.

No worries -- I had to think a bit to get to common units from the metric which is so much easier.
