The unit of measurement used to measure gravity (G's) is actually based off of Earth's gravitational pull; one G is the level of gravity on Earth.
Mass is the amount of matter. Weight had to do with gravity. Weitht is the force of gravity on mass. Some times we use gravity to measure mass such as a spring scale. That does not mean that gravity and mass are the same thing.
Gravity holds the planet together as a 'ball' and you on it. It also makes things fall. We can measure this so we know the force of gravity on earth and can calculate it for other planets and stars.
Weight is a measure of how strongly gravity attracts an object. Earth isn't the only thing that has gravity; all physical objects have gravity.
More mass = more gravity. From the movement of an object, rather from its acceleration, the mass of any object that attract it can be calculated.
A refractometer.
Refractometer
There are four main types of refractometers: traditional handheld refractometers, digital handheld refractometers, laboratory or Abbe refractometers, and inline process refractometers. There is also the Rayleigh Refractometer used (typically) for measuring the refractive indices of gases.In veterinary medicine, a refractometer is used to measure the total plasma protein in a blood sample and urine specific gravity.

Specific gravity.
An Abbe refractometer is an instrument used to measure the refractive index of a liquid, by utilizing the critical angle for total reflection.
Oceanographers measure the salinity of the ocean by hand held refractometer, hydrometer, and conductivity meter.
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.

It is spelled "density" and specific gravity is a measure of density and so does not need to be converted.
The density of urine
I believe the reason behind using specific gravity is that it is easier to measure (especially when you're measuring it for a solid).
