The unit for density can be anything as long as it is a unit of mass over a unit of volume. Usually it is expressed as grams/liter.
The density of one marble is the same as the density of six marbles when compared in terms of mass per unit volume. Since the density remains constant regardless of the number of marbles, the ratio of their densities is 1:6.
The unit of density is kilograms per cubic meter (kg/m^3) or grams per cubic centimeter (g/cm^3). The unit of relative density, also known as specific gravity, is dimensionless as it is the ratio of the density of a substance to the density of a reference substance (typically water).
Density unit is mass / volume. SI unit for dendity is kg/m3.
"kilometer" is a unit of length or distance, not a unit of density.
no
The SI unit for density is kg/m3In the CGS system, it is g/cci have no idea:P
Unit of density is 1kg/1000 cm3 because Density = Mass/Volume
The unit "g over m2" is not an SI unit for density. SI unit for density is kg/m3 or g/cm3 or g/mL, which all represent mass per unit volume. The unit "g over m2" represents mass per unit area, not mass per unit volume.
'Density' is not a unit at all. Density is how tightly atoms in an object are packed together. Therefore, density isn't a new unit, or a unit at all for that matter. The SI units of density are kg m-3. It common use the cgs unit g cm-3 is much more prevalent.
Density is mass/volume. So the unit of density is any unit of mass divided by any unit of volume. e.g. g/cm3.
Linear density refers to the mass per unit length of a one-dimensional object, such as a wire or string. Density, on the other hand, refers to the mass per unit volume of a three-dimensional object, such as a solid, liquid, or gas. Thus, linear density is a measure along one dimension, while density is a measure in three dimensions.
Depends upon the density of the subject (microgram is a unit of mass, mililitre is a unit of volume).
