In transport, the effective weight denotes the real weight of a commodity and is specified precisely. The effective weight serves as the basis for calculating the transport costs. However, if the transported goods are very large and have hardly any dead weight, the calculation of the costs is carried out with the volume weight, which indicates the required space requirement. For loads that require a lot of space, but are very light, otherwise, the transport costs would not be covered. The limit value must be determined differently for different modes of transport. The effective weight comes from a weight of 167 KG per cubic meter in the aircraft, 1000 KG by sea and 333 KG in trucks are used. For loads with less effective weight, the transport costs are calculated with the volume weight.
