Pounds relates to weight and gallons relates to volume, so you cannot compare the two of them.
density = mass / volumeso 0.78 (lbs/gal) = 500 lbs / volume (gal)500/0.78 = volume = 641.03 gallons
This depends on the mass of the material being measured. 500 pounds of steel will require fewer gallons than 500 pounds of aluminum.
That converts to 4000 pounds which is the same as 2 tons. 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.
500 gallons of pure water weigh 4,172.6 pounds (rounded) With 250 pounds of salt added, the mixture had better weigh 4,172.6 + 250 = 4,422.6 pounds, or else mass has disappeared, which is a no-no.
500 liters is 132.09 US gallons.
