Water seems to be related to gravity in the
same way that paper is related to wind.

The specific gravity of a substance (as an example, I'll take iron) is the density of iron divided by the density of water. Or some other reference substance - but usually the comparison is with water.
Your urine's specific gravity reflects the amount of minerals, solids, and wastes in the urine. Specific gravity is a comparison of urine's density to water's density.

Specific gravity of a mineral is calculated by dividing the weight of the mineral by the weight of an equal volume of water. This is typically done using a balance to measure the weight of the mineral and a graduated cylinder to measure water displacement. The specific gravity value provides information about the density and composition of the mineral in comparison to water.
Specific gravity (the lab slang is "spee gee") or SG is a comparison of the density of a material to the density of pure water (at about 4 degrees C, the point of its maximum density). To make a comparison, a basis for comparison had to be chosen. Why not pick water? It's a natural choice because it is a stable and universally available substance. It doesn't hurt that its density is right at (but not exactly) 1000 kg/m3 or 1 g/cc. That's just frosting on the cake.
This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.
Approximately 8.87 meter/second2. For comparison, Earth's gravity is approximately 9.82 meters/second2.

Density aka specific gravity is a measure of the amount of matter in a given volume. Actually specific gravity is not the measure of the amount of matter in a given value, it is a comparison of the density of the substance to water's density. Specific gravity is a unitless quantity.
Yes. Surface gravity on Ceres is about 3% that of Earth.
No. Turpentine does not sink in water. Like many oil based organic solvents, turpentine floats in pure water. Engineers and scientists use a measurement called Specific Gravity to measure how dense a liquid is in comparison to that of water. Pure turpentine has a Specific Gravity of 0.85(@25 deg Celsius). On the other hand, water has a specific gravity of 1.0. That means that turpentine at will eventually float to the top of a water bath.
