density is measured in grams per liter (g/L)
Density is mass/volume, which is a ratio of mass per unit of volume. The SI derived unit for density is kg/m3, but in chemistry it is measured primarily in g/cm3 or g/mL. 1cm3 = 1mL.
What measures density
Viscosity and density are both physical properties of a substance that describe how the molecules interact with each other. Viscosity measures a fluid's resistance to flow, while density measures the mass of a substance per unit volume. Both properties are influenced by the molecular structure and composition of the substance.
density= mass/volumedensity
Milligram is a unit of mass, milliliter is a unit of volume, so these really measure different things. For a specific substance, you can do the conversion if you know the substance's density (mass per unit of volume).
It is a measure of mass per unit volume and is derived using measures of mass and lengths in three orthogonal dimensions.
The two main types of population density are arithmetic population density, which measures the number of people per unit of area, and physiological population density, which considers population density in relation to the amount of arable land available for agriculture in an area.
The characteristic property that measures a substance's mass per unit volume is density. Density is typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
A gram is a unit of mass. A millilitre is a unit of capacity. Without some unit of density to compare, the two units are therefore incompatible.
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.
