Neither, a bathtub weighs much more.
i think it is 1 pints that the 2 gallon weighs because there is 8 pints in a gallon and so if you times 8 by 2 and that will be16 and then that will be the weight of the 2 gallons.
gallons are not a unit of measurement for weight. that would be most definitly 10000000000000000000000000000000000000000000000000000 gallons
716 quarts
About 1,670 pounds for 200 US gallons.
It is usually in ml. in Canada
5 gallons of cement would weight 5 * the weight of 1 gallon
Clear ice weighs about 7.6 lbs per gallon so 21 gallons would weigh about 160 lbs.
Five gallons of sand would actually weigh more than five gallons of water.
One gallon of water weighs about 8.33 pounds. So 67,230 gallons would weigh around 560025.9 lb.
40 pounds
That isn't a matching conversion. Pints are a measure of liquid volume. Pounds is a measure of weight/mass. They don't convert directly because of density. If you weighed the same as water, you would be 200 pints. But the human body is lighter than water, so it would be more, say 220 pints.
It depends what substance you have 305 gallons of. 305 gallons of mercury would weigh a great deal more than 305 gallons of petrol
