About Density Calculations

Density (ρ) is a fundamental physical property of matter, defined as mass per unit volume. The density formula is:

ρ = m/V

Where:

• ρ (rho) is the density
• m is the mass of the substance
• V is the volume it occupies

Common Material Densities (at 20°C):

Material	Density (kg/m³)	Density (g/cm³)
Water	998	0.998
Ice	917	0.917
Aluminum	2,700	2.70
Iron	7,870	7.87
Gold	19,320	19.32
Air (at sea level)	1.225	0.001225

Applications of Density Calculations:

• Determining material purity and composition
• Buoyancy and flotation calculations
• Metallurgy and material science
• Fluid mechanics and hydraulics
• Quality control in manufacturing
