What is kilograms per cubic metre?

Kilograms per cubic metre (kg/m³) is a unit of measurement for density. It is commonly used to measure the mass per unit volume of a substance or material. For example, the density of water at room temperature is approximately 1000 kg/m³, while the density of air at sea level is approximately 1.2 kg/m³. It is important to note that density can vary depending on factors such as temperature, pressure, and composition. In some industries, such as construction and engineering, kg/m³ is used to determine the weight and volume of materials needed for building structures and infrastructure.
