Specific gravity of urine is a measurement of the concentration of urine. The higher the specific gravity, the more concentrated urine is. The measurement is similar to osmolarity. This measurement is used in drug testing to see if someone drank a lot of water before the drug test in an attempt to dilute drug metabolites.
Specific Gravity= Density of Liquid (g/mL)/ Density of water (1.00 g/mL)
----------------------------------------------------------------------------------------------
Sp gr = weight of the substance / weight of an equal volume of water
or,
Sp gr = density of the substance (g/mL) / density of water (1.00 g/mL)

Specific Gravity is a unitless number (dimensionless quantity.) It is the ratio between the density of the material of interest and a standard material (e.g. water at it's greatest density). The units cancel out leaving a numerical value only.
Using gold as an example:
Density of gold: 19.3 g/cm3
Density of water at 4oC: 1 g/cm3
Specific Gravity of gold:
(Density of gold)/(Density of Water)=(19.3 g/cm3)/(1 g/cm3)=19
It is the ratio of the density of a material to that of water at 4 degrees Celsius.
It's the same as the number of kilograms per liter.
Comment'Specific gravity' has, for some time, now, been called relative density.
Specific gravity is defined as the ratio of the density of a given solid or liquid substance to the density of water at a specific temperature and pressure, typically at 4°C (39°F) and 1 ATM (29.92 inHg) , making it a dimensionless quantity (see below). Substances with a specific gravity greater than one are denser than water, and so (ignoring surface tension effects) will sink in it, and those with a specific gravity of less than one are less dense than water, and so will float in it. Specific gravity is a special case of, or in some usages synonymous with, relative density, with the latter term often preferred in modern scientific writing. The use of specific gravity is discouraged in technical use in scientific fields requiring high precision - actual density (in dimensions of mass per unit volume) is preferred.
Specific gravity is the ratio of the weight in air of a given volume
of a material at a standard temperature to the weight in air of an equal volume of distilled water at the same stated temperature.
For Sandy soil, i.e. soils mostly made of quartz, Specific Gravity can be accurately estimated to be about 2.65, whereas for silty and clayey soils, it may vary from 2.6 to 2.9.
The specific gravity is a number that denotes how much a material is denser than pure water at 4°C. Pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/litre, or 1000 kg/cu.m at 4°C.
To answer the asked question, the formula for specific gravity is:
sg = m/mw
where:
Specific Gravity is calculated by dividing the mass of the object (usually liquid) by the mass of an equal volume of water. You can substitute hydrogen, oxygen, or common air (if exact mass and volume are known) when performing the calculation with gasses.
Remember that specific gravity is a ratio (by its definition in physics), and so the answer will change depending on what you're comparing the sample object to.
specific gravity is a parameter which tells you about the relative weight of the material with respect to the same amount of water.
Specific gravity of an object is the density (= mass/volume) of the object compared with the same measure for water.
specific gravity of acetone is 0.79
The specific gravity of a product can be found on the material
The specific gravity of a substance is the ration of its density to some standard, almost always water for liquids or solids. In this case, Feldspar has a specific gravity of about 2.6.
There is a very great relationship between density and specific gravity. Density contributes to the weight of a substance under specific gravity.
Almost, but not quite. 'Specific gravity' is the density of a substancecompared to water.Numerically . . .Specific gravity of a substance = Density of the substance/Density of water.
10 dude :)
normality= weight/specific gravity*100/assay
depth*area=volume volume/specific gravity=total tonnage
The specific gravity of diamond is 3.5, which is 'above average'.
There is no such thing as a specific gravity for any element.
First, you have to calculate the ball's volume. Just divide the mass by the specific gravity. Then use the formula for the volume of a sphere. Solve for r (radius). The diameter is twice the radius.
Aluminum has no specific gravity, at least by the current definition of gravity.
helium doesn't have a specific gravity
mica has the specific gravity of 2.88

The specific gravity of lithium is 0.534
Specific gravity of ppc is 3.15
