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 for ...
specific gravitywood densityThe specific gravity of wood is its single most important physical property. Most mechanical and physical properties of wood are closely correlated to specific gravity and density. The physicomechanical properties of wood are mainly determined by three characteristics: (i) ...

Density and Specific Gravity (1)Density (r) of a material is defined as mass per unit volume and is usually represented in the SI system by the units g*cm-3 or kg*m-3. There are a number of different methods and devices for determining the density of a substance, and there are also...
Specific gravity values aren't very useful except for predicting whether or not something will float on water and for comparing whether one material 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 ...

Bulk specific gravityresults have also been reported in the literature, from which an average value of 0.9 has been determined (13 samples). However, the results appear to be bimodally distributed and split into two groups: one varying from 0.4 to 0.7 and the other from 1.3 to 1.5. This ...
JE crois que la notion de specific gravity donnée par M. Cumming dans NATURE du 19 avril (vol. xxxvii. p. 584) est de nature à puzz'er les étudiants plus encore que la vraié définition physique de la densité. This is a preview of subscription content, access via your institution...
