Freight calculators

Three quick sums that come up in every quote. They give estimates: carriers apply their own rules and rounding, and the figure on your quote is the one that counts.

01

Volume in cubic metres

Volume = length x width x height of one package, in metres, times the number of packages. In centimetres: multiply the three sides and divide by 1,000,000.

Enter the sizes to see the volume.

For scale: a 20ft container holds about 33 m3, a 40ft about 67 m3. See container types.

02

Air chargeable weight

Airlines charge on the greater of actual weight and volumetric weight. The usual air cargo convention is 6,000 cubic centimetres to one kilogram: volumetric weight = length x width x height in cm / 6,000, per package. Express couriers often use 5,000.

Enter the sizes and weight to see the chargeable weight.

03

Sea freight: weight or measure

Part-load (LCL) sea freight is usually charged per revenue tonne: the greater of the volume in cubic metres and the weight in tonnes. One cubic metre is weighed against 1,000 kg.

Enter the volume and weight to see the revenue tonnes.
