Specific gravity is the density of a substance, compared to the density of water. Density is defined as mass / volume. It is not directly related to weight. Although many people tend to confuse "weight" with "mass", they are really different things.
To calculate weight using specific gravity, you multiply the specific gravity of the substance by the weight of the substance in air. This gives you the weight of the substance in a vacuum.
"Weight" refers to the force of gravity acting on an object.
"Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such. So, you would have to specify, "specific gravity [or density] of what substance"."Relative gravity" is used more or less as a synonym for density; it bears no direct relation with "gravity" as such.

Specific gravity.
The unit weight of soil with a specific gravity of 2.65 is 1.8 g/cc.
The weight of a mineral is compared to the weight of an equal volume of water using a measurement called specific gravity. Specific gravity is the ratio of the weight of the mineral to the weight of an equal volume of water. Minerals with a specific gravity greater than 1 are heavier than water, while those with a specific gravity less than 1 are lighter.
This ratio is called the specific gravity.
The measurement of weight is affected by gravity.
Dry Bulk Specific Gravity does not take into account for anything getting into the permeable or impermeable voids of say a stone by water for instance. Saturated Surface Dry Bulk Specific Gravity takes into account for anything getting into the permeable voids only of say a stone by water. Apparent Specific gravity takes into account for the volume of the impermeable voids and not anything getting into the permeable voids of say a stone by water.
density is like weight and gravity is what pulls you to the ground density is what determines weight
