What is Most correct way to express density?

Answer 1

Density is described by mass per unit volume.

The equation for density is ρ = m/v

where:

ρ = density

m = mass

v = volume

The SI unit is kg/m3 (this is widely used) or g/cm3

The imperial (U.S.) unit is lb/ft3 or slugs/ft3

Some useful conversions:

1000 kg/m3 = 1 g/cm3 = 1000 g/L = 62.4 lb/ft3

Answer 2

The density of an object is the mass per unit of volume of the object.

Answer 3

The SI unit is Mg/m3; frequently used are g/cm3 and g/L.

Answer 4

g/cm^3
