Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. So the units cancel each other out. Specific gravity is used as an indicator of the state of charge of a cell or battery. However, because the density of pure water is Densities and Specific Weight of Water in Imperial Units Weight per US gallon is based on 7.48 gallons per cubic foot . • Put sample of wine into test jar ensuring there is enough for the hydrometer to float freely. N    So the specific gravity of gold is 19.3. Specific gravity is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Then, divide this density by the density of pure water in the same units. In homework, this is usually assumed to be the reference substance when working with liquids. In this article, we shall make the formula or relation between the dry unit weight (), specific gravity(G), percentage of air voids and water content (w). Urine Specific Gravity: The Urine Specific gravity (USG) is measured and used mostly in veterinary sciences to understand whether water is excreted or conserved in an appropriate fashion. Density varies with the units of measure used (e.g. Gas Specific Gravity relative to Air at 70˚F Liquid Specific Gravity relative to Water @ 60˚F Acetylene C 2H 2 0.911 Acetone 0.792 Air - 1.000 Alcohol, Ethyl (100%) 0.789 Ammonia NH 3 0.596 Acid, Muriatic (40%) 1.200 Anthracite What are the units for specific gravity? Moreover, in thi9s topic we will discuss specific gravity, specific gravity formula and its derivation and solved examples. Therefore, specific gravity has no units. From: Canine and Feline Nephrology and Urology (Second Edition), 2011 For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/m³). Calculating volume of a fluid: The fluid’s volume can be calculated using the specific gravity of the fluid and the weight. Click here for instructions with pictures on how to use a hydrometer. In more general terms specific gravity is the ratio of the density of a material to that of any standard substance, although usually this is water at 4 degrees Celsius or 39.2 degrees Fahrenheit. A hydrometer is a tool used to measure Specific Gravity (S.G.) which is imperative to monitor throughout the winemaking process to keep track of fermentation. The density of ketchup is 1,400 kilograms per meter cubed. Specific gravity is a measure of a material’s density (mass per unit volume) as compared to the density of water at 73.4 F (23 C). Note: 1. wt. Specific Gravity (Relative Density) - SG - is a dimensionless unit defined as the ratio of the density of a substance to the density of water - at a specified temperature and can be expressed as.
