Water was used as the standard because at first, the cubic centimetre was defined so that pure water, at 4 deg C and a pressure of 1 bar, had a density of 1 gram per cubic centimetre. The specific gravity of other substances, being the ratio of their density to that of water, meant that their specific gravity would have the same numeric value as their density. However, an error in defining the centimetre resulted in a change in its definition and the density of water is no longer 1 g/cm3.

How do you convert specific gravity 0.8349 to pounds per gallon?
For this I will use water as the unit of measure. Based on the lbs per gallon of water @ 4 degrees Celsius which is 8.33 8.33 is a specific gravity of 1 The equation to determine lbs per gallon using a basis of water lbs per gal = (sg * 8.33) So if you have 0.8349 as your specific gravity: (0.8349 * 8.33) = 6.954717 (lbs per gal) The equation to convert pounds to gallons of a different fluid that has a variable specific gravity would be: gallons = lbs / (sg * 8.33) If I have 5 pounds of a lubricant with a SG of 1.2 5 / (1.2 * 8.33) = 0.5 (gallons) http://www.engineeringtoolbox.com/water-gallons-pounds-d_1710.html
Api gravity to pounds per gallon?
Well, darling, API gravity is a measure of how heavy or light a petroleum liquid is compared to water. To convert API gravity to pounds per gallon, you'll need to use a specific formula that takes into account the density of water and some other fancy factors. So, grab your calculator and get ready to crunch some numbers if you want to make that conversion happen.

Purity of milk is measured by which instrument?
Lactometer is used t measure the purity of milk Lactometer is an instrument invented by Mr. Dicas, of Liverpool, for the purpose of ascertaining the different qualities of milk from its specific gravity compared with water. On this subject Dr. Ure observes, that it is not possible to infer the quality of milk from the indications merely of a specific gravity instrument, because both cream and water affect the specific gravity of milk alike. "We must first use as a lactometer a graduated glass tube, in which we note the thickness of the stratum of cream afforded, after a proper interval, from a determinate column of new milk; we then apply to the skimmed milk a hydrometric instrument, from which we learn the relative proportions of curd and whey. Thus the combination of the two instruments furnishes a tolerably exact lactometer."

Why use kerosene in the test specific gravity of cement?
Kerosene, a petroleum product will not interact chemically with Portland cement - water will.
How to determine specific gravity of oils?
The term specific gravity means density in comparison to that of water. Density is weight divided by volume. So to get the volume, pour the oil into a graduated cylinder or measuring cup (same principle). To get the weight, use a scale (a chemist would use a triple beam balance). Once you have the density you can divide it by the density of water, and the result is the specific gravity.
What is the expression for specific gravity when kerosene is used instead of distilled water?
Specific gravity is the ratio of density of material to the density of water, so when we use Kerosin instead of water then the value will be multiplied by the specific gravity of kerosin to get the actual specific gravity.
How do you measure specific gravity of sand?
Determine the density of the sand. Determine the mass of the sand, and it's volume. Divide the mass by the volume and that gives you density. Then divide the sand's density by the density of water. That will give you the specific gravity of the sand. Because you divide densities, the units cancel out, and specific gravity does not have any units. For example, you determine the density of the sand to be 10g/cm3, and the density of pure water is known to be 1g/cm3. Divide 10g/cm3 by 1g/cm3. The g/cm3 cancel, and you are left with just the number 10. So in this example the specific gravity of sand is 10.
How do you calculate pressure under water?
To calculate pressure underwater, you can use the formula: pressure density of water x gravity x depth. This formula takes into account the density of water, the acceleration due to gravity, and the depth of the water. By plugging in the values for these variables, you can determine the pressure at a specific depth underwater.
How do you prepare a solution of specific gravity 1.06?
To prepare a solution of specific gravity 1.06, you need to dissolve a substance in water that will give you that specific gravity reading. The most common substance used for this is sugar, where a concentration of around 5.55% sugar in water would give you a specific gravity of 1.06. Alternatively, you can use a hydrometer to measure the specific gravity and adjust the concentration of your solution until you reach the desired value.
Why do scientists use specific gravity instead of density?
Since specific gravity is an ideal quantitative respresetnation of the denstiy (kg/m^3) of a substance relative to the denstiy of distilled water, specific gravity can be used interchangably with measures of Osmolality (moles/1kg of solvent). This relationship is readily observed throughout the physical implications of homeostasis within the endocrine system.

How do you Determine the Specific gravity of cement?
Cement is usually purchased as a powdery substance that is mixed with sand, aggregate, gravel and water to form concrete. Since the cement itself is usually a powder, it is hard to measure a standard value for it's specific gravity. And since cement is usually not used by itself, knowing it's specific gravity is not particularly useful. A more useful question is "What is the typical density of concrete?" A rule of thumb answer is that normal cured concrete has a density of about 150 pounds per cubic foot. This includes the weight of the cement, sand, aggregate, and that part of the water that chemcially binds with the cement to form the concrete. Since water weighs about 62.4 pounds per cubic feet, concrete is about 2.4 times as heavy. Thus the specific gravity of concrete is about 2.4. If you took cement and mixed it with water, you would eventually have a hard lump of useless cement and it would also have a specific gravity of between 2 and 2.4. Ash Grove Cement from the Foreman, AR Facility normally has a specific gravity of 3.15. Depending on the source of the cement, the specific gravity may vary, but typically it will be close to this figure. Knowing the specific gravity of cement is critical when developing a mix design for concrete, because if one does not know the specific gravities of the raw materials, it is not possible to figure the proportions needed to give you the appropriate yield for a cubic yard of concrete.
Would turpentine settle to the bottom when mixed with water?
No. Turpentine does not sink in water. Like many oil based organic solvents, turpentine floats in pure water. Engineers and scientists use a measurement called Specific Gravity to measure how dense a liquid is in comparison to that of water. Pure turpentine has a Specific Gravity of 0.85(@25 deg Celsius). On the other hand, water has a specific gravity of 1.0. That means that turpentine at will eventually float to the top of a water bath.
How can i use the word hydrometer in a sentence?

What's the relationship between Specific retention and specific yield?
Both Specific retention and specific yield relate to the ratio of the volume of water (in a permeable unit of rock and/or sediment) to the total volume of the rock and/or sediment, as it relates to gravity. Specific retention is the ratio of the volume of water that is RETAINED against the pull of gravity, ...where-as specific yield is the ratio of the volume of water that is EXPELLED (yielded) against the pull of gravity. Again, ...both as a ratio to the total volume of the rock and/or sediment.
