How to convert pounds per cubic foot to kilograms per cubic meter
Density connects mass and volume for a specified material and state. Specific gravity needs a reference density and is not directly treated as a density unit.
Use x for the value in lb/ft³, b for the intermediate value in kg/m³, and y for the result in kg/m³.
kg/m³ = lb/ft³ × 16.018463373960138
Worked examples
10 lb/ft³ ≈ 160.18463374 kg/m³
Step 1: (10 × 16.018463374) ≈ 160.18463374 kg/m³.
Step 2: 160.18463374 ÷ 1 ≈ 160.18463374 kg/m³.20 lb/ft³ ≈ 320.369267479 kg/m³
Step 1: (20 × 16.018463374) ≈ 320.369267479 kg/m³.
Step 2: 320.369267479 ÷ 1 ≈ 320.369267479 kg/m³.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Pounds per cubic foot
Pounds per cubic foot (lb/ft³) measures density under the conventions above. The base value in kg/m³ is (x × 16.018463374), where x is the numerical value in lb/ft³. Factors shown here are rounded for display; calculations use the stored factor.
