Conversion of voulme to weight

[Curious]

Does the density of matter alter the wieght of a given volume? In other words, would a gallon of water weight the same as a gallon of sand or any other substance?

Since density is defined as the weight of a unit volume and different substances have different densities, obviously, it is different. Before you put anything in it, your bucket is full of air, which weighs a little, not much, water weighs more, sand concrete, lead weigh a lot more than water.

You can't "convert" mass to volume without knowing density, and density is a property specific to the material, but changes with temperature and pressure for a given material.

No it wouldn't weigh the same. We are dealing with area to weight. The area a gallon of liquid would use is a known variable. The weight will change with the material that is placed in the known area. For instance,
the area of a gallon of water would be the same as the area of a gallon of Mercury, however the weight of the to materials would be different!!

The volume (meaning the size of an object) is differnt than the weight of an object.
in simple terms oil and water. Lets say two normal gallon jugs of the exact same size, if you poured water in one and oil in the other one.
You would find that a gallon of water fills the jug to the top, has the oil would not be filled to the top mabe only 60%. Thus meaning water weighs less than oil but has a bigger volume(size). Sometimes when manufacturers give out specs they give it out in volume or weight not all the time both.
