For true (in vacuo) relative density calculations air pressure must be considered (see below) Temperatures are specified by the notation (T s /T r) with T s representing the temperature at which the sample's density was determined and T r the temperature at which the reference (water) density is specified For example, SG (20 °C/4 °C) would.

Density is how much matter is contained within a volume A dense object weighs more than a less dense object that is the same size An object less dense than water will float on it; one with greater density will sink The density equation is density equals mass per unit volume or D = M / V.

Bulk density is the mass of bulk solid that occupies a unit volume of a bed, including the volume of all interparticles voids Taking into account that a powder is really a particle gas mixture with both interparticle spaces and intraparticle voids (Fitzpatrick et al, 2013), three classes of bulk density have become conventional: aerated, poured, and tap.
