Kilogram per Cubic Meter (kg/m³) – The SI Standard for Density

Thekilogram per cubic meter (kg/m³)is the standard unit of density in the International System of Units (SI). It represents the mass in kilograms contained in one cubic meter of a substance.

History & Background:As part of the SI system, kg/m³ was adopted globally during the development of the metric system. Its use allows for consistent scientific calculations and comparisons across various fields, including engineering, chemistry, and physics.

Applications:- Widely used in material science to measure the density of liquids, solids, and gases.
- Crucial in engineering for designing structures and calculating load-bearing capacities.
- Essential in environmental science for analyzing atmospheric and oceanic densities.
