How it works
What the figures mean
Volume
Length × width × height of each package, times the quantity, in cubic metres (m³). One cubic metre is 1,000,000 cm³ or about 35.3 cubic feet.
Container fit
How full each container would be, by its inside volume and by its payload; when your cargo needs several containers, the average over them. For one package size the calculator counts how many fit in tidy rows through the door, without gaps, so large packages can need more containers than their volume alone suggests; for several sizes it assumes that about 85% of the space can be used, a common rule of thumb for mixed cartons.
Air freight
Airlines charge the greater of the actual weight and the volumetric weight: the volume in cm³ divided by 6,000, about 167 kg per cubic metre, the IATA standard. Courier services often divide by 5,000.
LCL sea freight
When your cargo shares a container with others (less than container load), the freight is charged per freight ton: the greater of the volume in cubic metres and the weight in tonnes, often with a minimum of one.
A planning estimate
The real loading also depends on how strong and stackable the packages are, how they are secured and on the container itself: its own payload, and the weight allowed on the road, can be lower than the figures used here. Ask us before you book.
