Work out shipping weight (dimensional) instantly with clear inputs, formula shown and shareable results.
Carriers charge on whichever is greater: actual weight or volumetric weight, calculated as length times width times height divided by a dimensional divisor — 5000 for most international courier services, giving an effective density of 200 kg per cubic metre.
Volumetric weight
volumetric kg = L x W x H (cm) / divisor; chargeable = max(actual, volumetric)
They encode the density a carrier considers break-even. 5000 is standard courier, 6000 for airlines under IATA rules and 4000 for some domestic express services.
Reduce the box to fit the contents. Every centimetre of void space is charged as if it were product at 200 kg per cubic metre.
