The term "volumetric weight" comes from the fact that the board of any aircraft has a limit of space. For example, the plane carrying capacity is 30,000 kg, and the total volume of its cargo compartments is only 120 cubic meters. In this case, it is clear that to carry out air freight airline interesting 30.000 kg heavy load (for example, steel molds) 120 m3 of volume of cargo (eg, diapers). Thus, the term "bulk cargo" was introduced to bring the relationship weight / volume of cargo to a common denominator
The coefficient for calculating the volume weight for air travel: 6 cubic meters per metric ton, ie 1 m3 = 167 kg payable weight.
Here is a scheme for calculating the volume of cargo:
- It is necessary to calculate the volume of each box in meters, ie, length * width * height multiplied by the number of boxes you will get the amount of your cargo
- Next, multiply the volume by a factor of 167 and obtain the volume weight. It may be more than the actual total weight of the load. If so, then the volume weight, and will be paid, that is to calculate the air delivery airfare must be multiplied by the volume weight.
3 boxes with size of 120*60*90 cm and weight of 40 kg each must be delivered
Apply sizes of one box in meters and multiply:
1,2*0,6*0,9 = 0,648 m³ (volume of one box).
0,648*3 = 1,944 m³ (volume of 3 boxes).
Multiply the amount by 167, we get:
1,944*167 = 324 kg (volumetric weight).
We see that it is more than the actual weight of three boxes (120 kg). Thus, the chargeable weight is 324 kg. That is, the airfare is multiplied by the chargeable weight 324 kg.,
