How to use this data

1 lb/ft³ = 0.45359237/0.028316846592 kg/m³. Physical mass = density × volume; this is separate from billable dimensional weight.

CHECK THE METHOD

Worked example

10 lb/ft³ equals about 160.185 kg/m³. At 2 m³, physical mass is about 320.369 kg.

Common lookup questions

What should I confirm before using this lookup?

Density does not establish freight class. Packaging, handling, liability and current carrier commodity rules need separate confirmation.
