About CBM & chargeable weight

What is CBM?
CBM is cubic metres — the volume of your shipment. For each item, CBM = length × width × height (in metres); for boxes measured in centimetres, multiply the three sides and divide by 1,000,000, then by the quantity. It’s the number freight is quoted and loaded by.
What is chargeable weight?
Carriers charge on the greater of the actual (gross) weight and the volumetric weight, because a light but bulky shipment still fills the vehicle. This tool shows both and takes the greater as the chargeable weight.
How is volumetric weight calculated?
Volumetric weight = volume ÷ a divisor set by the mode: 6000 for air freight, 5000 for express/courier (with dimensions in centimetres). Road and sea usually charge by CBM or loading metres instead.
What are loading metres (LDM)?
Loading metres are how much of the length of a standard 2.4 m-wide trailer your goods take up on the floor. This tool estimates LDM from the footprint of your items, assuming they are not stacked — stackable goods take fewer.
