7.5 pounds is how many gallons?

Answer 1

None, since there can be no conversion.

A gallon is a measure of volume. A pound is a measure of mass. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

Answer 2

That depends on the type material you are referring to. Please edit your question to include more context or details.

Answer 3

A gallon is a unit of capacity. A pound is a unit of mass. Without some unit of density to compare, the two units are incompatible.

Answer 4

The number of gallons in 7.5 pounds depends on the density of the substance. For water, which has a density of 8.34 pounds per gallon, 7.5 pounds would be approximately 0.90 gallons.

Answer 5

There is 1.98 gallons in 7.5 liters
