Specific gravity it the ratio of the mass of something divided by the mass in
an equal volume of water.Something with a specific gravity of 2 is twice as
heavy as water. relative mass is the same thing but the numbers in your chart
are not measured against water but use something else as a standard.

If they were different brands with a slight diffrence in proof could make a
difference also the temp of the sample can change specific gravity as things
are more dense when cold.
