Density is measured as #mass/volume#. The SI unit for density is #kg/m^3# or kilograms per meters cubed. Density, however, can be measured in a wide variety of units, like #g/cm^3# or #g/mL#. Density = Mass/Volume. The units for density are grams per cubic centimeter ( #g/cm^3#** ) or grams per milliliter ( #g/mL# ), since a cubic centimeter is equivalent to a milliliter.

Density it the relationship between the volume and mass of a substance. Specifically, it is found by dividing the mass by the volume. The unit of density depends upon which units are used to measure mass and volume.

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume:

Mass is a measurement of how much matter there is in a substance. This is often found using the units grams or kilograms. Volume is a measurement of how much space a substance occupies. Cubic centimeters and cubic meters are typical units of volume. Therefore, density is commonly identified using the units grams per cubic centimeter or kilograms per cubic meter.

What is Density? The density of an item is quantity of that item per unit measure, especially per unit length, area, or volume. In natural resource measurements, density is usually used to refer to the number of items per unit area. For example, plants/m2 or elk/hectare). The term abundance is often used as synonymous with density.

The ratio of mass to volume of a substance is called density. Units of measure for density include kilograms per meter cubed and grams per centimeter cubed.

where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight.

The reciprocal of the density of a substance is occasionally called its specific volume, a term sometimes used in thermodynamics.
https://en.wikipedia.org/wiki/Density
For example, water has a density of #1 g/mL# or #1 g/cm^3#. What this means is that for every #1# gram of what you have, it takes up #1# milliliter of space (or #1# cubic centimeter). If you were to put #1# milliliter of water in a test tube and find its mass, it would be exactly #1# gram.

Density in vegetation measurement refers to the number of individuals per unit area (for example plants/m2). The term consequently refers to the closeness of individual plants to one another. The measure of density is often applied when we want to monitor changes in a given vegetation species over long periods.
