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.

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