WebIl concetto di densità è essenziale nelle equazioni di bilancio . Nel Sistema Internazionale la densità si misura in kg / m³; nel sistema CGS in g / cm³ . Nell'uso comune si utilizza talvolta il kg/ L o equivalentemente in g/ mL, che corrispondono esattamente a g/cm³.

Density (volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: See more In a well-known but probably apocryphal tale, Archimedes was given the task of determining whether King Hiero's goldsmith was embezzling gold during the manufacture of a golden wreath dedicated to the gods and … See more A number of techniques as well as standards exist for the measurement of density of materials.
