SECTION 58 – SPECIFIC GRAVITY AND DENSITYW.J. ROFFJ.R. SCOTTFibres Films Plastics & Rubbers
What is specific gravity? Discover the definition of specific gravity and its connection to density. Explore how to convert between units and the instruments used to measure it.
The difference between density, specific weight, and specific gravity. Including formulas, definitions, and reference values for common substances. Density is defined as mass per unit volume . Mass is a property and the SI unit for density is kg/m3. Density can be expressed as ρ = m / ...

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....
SPECIFIC GRAVITY Density (D) -The mass (or weight) per unit volume of a material at a given temperature. Typical units are: grams per cubic centimeter (g/cc or g/cm3) kilograms per cubic meter (kg/m3) pounds per cubic foot (lb/cu ft or lb/ft3) pounds per cubic inch (lb/cu in...
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...

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.
