Specific Gravity or relative gravity is a dimensionless quantity that is defined as the ratio of the density of a substance to the density of the water at a specified temperature and is expressed as S G = s u b s t a n c e H 2 O Specific Gravity = Density of substance / Density of equal amount of water. If a species is not footnoted with a number (1-18), then the specific gravity for that species has not been verified by Wagner. Substance / Specific Gravity (Typical) 1 kg/m3 = 0.0624 lb/ft3 = 0.000036127 lb/in3 Source Important Comment: The above information is presented free of charge by READE and on a "best efforts" basis toward being accurate. Put cup of water on the scale and zero the scale Step 3. Many stackers are concerned about fakes. Obviously, since the range of values generally shows an increase in density, one of the common "contaminants" is gold. To participate in the forum you must log in or register. For example : 32 Baume equals a sp. g. = 144.3/144.3 - degrees Baume. However, like gold, silver is rarely found in the pure form. Thanks also to the new channel sponsor The Silver Forum!www.thesilverforum.com (5. Expect a range of values from 10 to 12, depending on the amount and type of impurity. Ailanthus altissima. As specific gravity is just a comparison, it can be applied across any units. Water, sea. The best time to get a sample is first thing in the morning, when your urine is the most concentrated.
