Q & A: What is specific gravity? | Department of Physics ...

The specific gravity ("Sp.G.") of a liquid tells you how much more or less dense the liquid is than water. Water has a specific gravity of 1.000 (near 4°C). If a liquid is more dense than water, then its specific gravity is greater than 1.

Specific Gravity: How to Measure it When Brewing Beer

The Specific Gravity of a liquid is that liquid's density compared to water. A liquid with a Specific Gravity of 1.030 is 1.03 times the density of water, for instance. In the case of your beer, there are several factors which can contribute to the density of your wort before fermentation and of your beer when it is finished fermenting.

Relative density - Wikipedia

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. The term "relative density" is often preferred in scientific usage.

How to Determine Specific Gravity of Soils

The density bottle method is used for the determination of specific gravity of fine-grained soils. It may be also used for medium- and coarse-grained soils provided that the soil is pulverized and passed through a 4.75-mm IS sieve. The density bottle is a pycnometer of 50-mL capacity with a stopper.
