What is Specific Gravity? 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. By definition, water has a density of 1 kg per litre at this temperature. The specific gravities of gases usually are compared to dry air which generally has a density of 1.29 g per litre. The specific gravity of all other materials is compared to water as a fraction heavier lighter or heavier density.

Measuring Specific Gravity Modified on: Mon, 21 Mar, 2016 at 12:51 PM. Specific Gravity: The most accurate and direct way to test the state of charge of a battery cell is to determine the specific gravity of the battery electrolyte. The higher the specific gravity of the electrolyte the higher the state of charge. The best way to truly monitor your system over it lifetime is to regularly take and record specific gravity readings.

specific gravity An object with a density of 85 kg/m3 has a specific gravity of 0.085, and will float high on the surface of a body of water. An object with a density of 85 g/cm3 has a specific gravity of 85, and will sink rapidly. To find the specific gravity of a gas, you must know its density in kilograms per meter cubed (kg/m3).

What is Specific Gravity? - Definition, Formula, Calculation & Examples When the specific gravity is greater than one, the object will sink, and when the specific gravity is less than one, then the object will float. If the specific gravity is equal to one', this means that the object will neither sink nor float -- it will hover in the liquid.

Specific weight Not to be confused with specific gravity. The specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma). A commonly used value is the specific weight of water on Earth at 5°C which is 9.807 kN/m3 or 62.43 lbf/ft3. The terms specific gravity, and less often specific weight, are also used for relative density.

Urine Specific Gravity Urine specific gravity test. Urine specific gravity is a laboratory test that shows the concentration of all chemical particles in the urine. After you provide a urine sample, it is tested right away. The health care provider uses a dipstick made with a color-sensitive pad. The color the dipstick changes to will tell the provider the specific gravity of your urine. The dipstick test gives only a rough result. For a more accurate result, your provider may send your urine sample to a lab. Your provider will ask you to temporarily stop taking any medicines that may affect the test results.

How to Calculate the Specific Gravity of a Substance Therefore, the specific gravity of gold is simply 19.3. Anything with a density greater than 1,000 sinks in pure water at 4 degrees Celsius, and anything with a density less than 1,000 floats. As you’d expect, gold, with a density of 19,300 kg/m 3, sinks. Ice, on the other hand, with a density of 917 kg/m 3, floats.
