One gallon is equal to how many pound?

Answer 1

Gallons are a measure of space whereas a pound is a measure of gravitational attraction, therefore there is no direct conversion. Even for a particular substance, such as water, there is no exact number, because heat expansion will change the amount of space that a given amount of water will fill. Also, there are some variances in atmospheric pressure (gallon in space /= gallon on earth) which can cause lesser discrepancies. So, to get an answer, you would have to specify the material, the temperature, and to a lesser extent the atmospheric pressure (if it is significantly different from 1 atm)

Answer 2

This cannot be answered without knowing what is being weighed. A gallon is a measurement of volume, where as a pound is a measurement of weight. A gallon of concrete is far heavier than a gallon of oxygen.

Answer 3

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 water. 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.

Answer 4

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

Answer 5

1 gallon equals 6.073 pounds
