It's basically equivalent to density. More precisely, it's the ratio of the density of a substance, to the ratio of water (or some other reference substance).
Specific gravity is a measure of density in comparison to the density of water (or air). A hydrometer is used for liquids but is not the only means. If you have a scale which can measure down to milligrams accurately, then by weighing one ml of the liquid you are checking will give you the specific gravity. specific gravity of water = 1 example: 1 milliliter of beer weighs in at 987 milligrams then the specific gravity is .987 . .987 g/ml / 1 g/ml = .987 (SpG)
Aluminum has no specific gravity, at least by the current definition of gravity.
specific gravity of fly ash is 3.2
Specific gravity doesn't have units. It's the density relative to water, so specific gravity is effectively just a number.
"Specific gravity" or "specific density"
no
Specific gravity.
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).
The specific gravity of a substance is the ratio of te density of the substance to the density of water. It is, therefore, a unitless measure.

Specific gravity I think. Start there.
An object will sink if its density - or its specific gravity - is greater than that of the fluid it is placed in.
Type of hydrometer used to measure the specific gravity of a urine sample
A refractometer.
