Density

Density is a physical property of a substance that indicates how much mass is present in a given volume. It is usually measured in kilograms per cubic metre (kg/m³) or in grams per cubic centimetre (g/cm³).

A higher density means that more mass is present in a given volume, while a lower density means less mass in the same volume. Density is an important parameter in various scientific disciplines, including physics, chemistry, materials science and geosciences, and it plays a central role in many calculations and experiments.
