Specific gravity is the ratio of the mass of a certain volume of a material to the mass of the same volume of water. This may be difficult to visualize, but think of it this way: Let's say that a block of metal has a specific gravity of 6.29. This means that the metal block weighs 6.29 times the mass of a block of water that is the same volume.
