Accuracy and rounding
Compare U.S. material density tables with SI engineering values.
Density units combine fixed mass and volume definitions. The numeric density of a real material can still vary with conditions.
For material calculations, keep enough kg/m³ precision for the final mass or volume and record the relevant conditions.

Common questions
How do I convert lb/ft³ to kg/m³?
Enter the lb/ft³ value in the converter, or multiply by the factor shown in the formula. 1 lb/ft³ = 16.0185 kg/m³.
What should I watch out for?
A material's density can change with temperature, pressure, moisture, or composition even though the unit factor is fixed.
