Definition It is the proportion of mass to volume. It is the relative proportion of the Density of the sample to the Density of the reference. Calculation To calculate the Density of any material weight and volume of the substance must be known. To calculate the specific gravity, the Density...
Since Specific Gravity - SG - is dimensionless, it has the same value in the SI system and the imperial English system (BG). SG of a fluid has the same numerical value as its density expressed ing/mLorMg/m3. Water is normally also used as reference when calculating the specific gravity ...
In my columns, I usually provide specific-gravity values for wood rather than density. Readers might wonder why. The answer is rather complex-but quite important-so I'm devoting a column to the subject. Density is defined as the mass per unit volume of an object. Mass and weight as ...
1、specific weight = weight/volume就是比重，单位是 （N/m^3或者 lb/ft^3）而gravity 指的是地心引力,所以不是用力来算的,而是用密度,所以,specific gravity=density /density of water @4 摄氏度，可翻译为相对密度。2、,没有单位（无量纲）。
(2.2)Density(kg/m³)=(specificgravity)×997.6 Sometimes the plastic being measured is sensitive to water. Method B of ASTM D792 allows the use of other liquids. In that case the density of the liquid, d, is added to the calculation as shown in Eq. (2.3): (2.3)Specificgravity=a×...
Density to Specific Gravity Conversion Specific gravity (SG) is a lot simpler than you and your alien friends expected: It's just the ratio of the density of a given object to the density of waterat a specific temperature.Specific gravity has no units.Its utility lies in the fact that the...

is more or less dense than another. However, because the density of pure water is so close to 1 (0.9976 grams per cubic centimeter), specific gravity and density are nearly the same value so long as the density is given in g/cc. Density is very slightly less than specific gravity....

This chapter discusses the density of a substance is the ratio of its mass to its volume. It is always necessary to state the units of density because it may be expressed in a number of different mass and volume units. Specific gravity is the ratio of the mass of a volume of a substan...
