It is the quantity that relates the mass and volume that a given material occupies in a space. Density expresses the amount of matter per unit volume of a given material. Lead, for example, is denser than water, which means that in a given volume of lead there is a greater concentration of matter than in an equivalent amount of water.

|Ounce per Gallon (oz/gal)|
|Pound per cubic foot (lb/ft³)|
|Pound per cubic inch (lb/in³)|
The density is calculated by the following expression:
The International System of Units (SI) uses the kilogram per cubic meter (kg/m3) to represent the unit of measure for density. Other ways to represent this quantity are grams per cubic centimeter (g/cm3) or in grams per milliliter (g/mL).
1000 Kg/m3 = 1 g/cm3 = 1g/mL
