Answer: 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 / V = 1 / ν [1]
where
ρ = density [kg/m3], [slugs/ft3]
m = mass [kg], [slugs]
V = volume [m3], [ft3]
ν = specific volume [m3/kg], [ft3/slug]
What is weight and what is mass? - the difference between weight and mass
The Imperial (U.S.) units for density are slugs/ft3 but pound-mass per cubic foot - lbm/ft3 - is often used. Note that there is a difference between pound-force (lbf) and pound-mass (lbm). Slugs can be multiplied with 32.2 for a rough value in pound-mass (lbm).
1 slug = 32.174 lbm = 14.594 kg
1 kg = 2.2046 lbm = 6.8521x10-2 slugs
density of water: 1000 kg/m3, 1.938 slugs/ft3

On atomic level - particles are packed tighter inside a substance with higher density. Density is a physical property - constant at a given temperature and pressure - and may be helpful for identification of substances.
