I haven't seen it in context, so I am not sure. However, I would expect it to mean, the density, compared to that of some other substance.
relative density methane
Relative density is determined by the ratio of the density of a substance to the density of a reference substance.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
relative density is related to the density of water. i.e. a relative density of 19.3 means that it has a density 19.3 times the density of water. The density of water is 1g/ml therefore the density of gold is 19.3g/ml
In SI system, unit of density is kg/m3 But no unit for relative density as it is the ratio of density of the material to that of water
the relation between relative density and density is that relative density of a substance is its density itself without its unit.

Relative to what. It has an mean density of 3.3464 g/cc.

Relative Density = 1,5
Relative density
The ratio of thee density of a substance of the density of a standard , usually water for a liquid or solid and aur for a gas. The SI unit of relative density is g/ m3
Relative density, is also called specific gravity, and it is the ratio of the density (mass/volume) of a substance to the density of a particular reference substance, usually water. So, where density has the units of mass/volume, relative density (specific gravity) is unitless.
