There is no equivalence.
A pound is a measure of mass. A gallon is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider a gallon of air. How many pounds? Next consider a gallon of Mercury. How many pounds?
The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
About 334 pounds for 40 US gallons.
22 kilograms is 48.5 pounds.
22 gallons x 15 miles/gallon = 330 miles
convert 20,000 gallons to pounds
That would be about 375 gallons. Pounds is a unit of mass/weight. Gallons is a liquid measure. They do not convert cleanly. The density of the liquid being measured can make a big difference. If the liquid is water, there is 8 pounds to a gallon.
Approximately 183.59 pounds.
42 gallons of water is 350.7 pounds
10 US gallons is approximately 83.5 pounds
30 pounds of water is 3.593 gallons.
About 250.5 pounds for 30 US gallons.
10 gallons of water is 83.5 pounds
800 pounds of water would be 95.8 US gallons.
That depends on what substance you have 227.5 pounds of.227.5 pounds of air fills many, many gallons.227.5 pounds of water fills about 27.2 gallons.227.5 pounds of granite fills only a few gallons.
