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 ...
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...
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）。
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 ...

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...
There are two primary units that tell you how dense a fluid is: Specific Gravity and API Gravity.
