Frequently asked questions
What does this result tell me?
Use gross mass and loaded external envelope including pallets where applicable. This does not assign NMFC freight class, carrier tariffs or chargeable dimensional weight.
How can I check the calculation?
Worked example: 400 kg gross shipment / 2 m³ occupied shipping volume gives 200 kg/m³, approximately 12.486 lb/ft³. Review each stated input and unit; use project-specific values rather than treating the editable example as a requirement.
