    Aluminum weight is calculated using the formula: Weight = Volume × Density. Aluminum has a density of approximately 169 pounds per cubic foot (2,710 kg/m³), which makes it roughly one-third the weight of steel. This low density-to-strength ratio is what makes aluminum the preferred material for aerospace, transportation, and lightweight structural applications.

    For flat aluminum sheets and plates, calculate volume as length × width × thickness, then multiply by density. For aluminum in inches, the density constant is 0.0975 lb/in³ — multiply length (in) × width (in) × thickness (in) × 0.0975 to get weight in pounds.

    Different aluminum alloys have very similar densities, typically ranging from 165 to 175 lb/ft³. For most practical calculations, 169 lb/ft³ works across all common alloys. The 6061-T6 alloy used in most structural and fabrication applications has a density of exactly 169.3 lb/ft³.
