Dimensions of weight , also known as volumetric weight , is a pricing technique for the carriage of commercial goods (including courier and mail services), using estimated weights calculated from length, width and high package.

Significance
Shipping costs are historically calculated on the basis of gross weight in kilograms or pounds. By filling only with heavy, light, low density packets it becomes unfavorable for transport operators because the amount of space they take on trucks/planes/vessels is proportional to their actual weight. The concept of dimensional weight has been adopted by the transportation industry around the world as a uniform means to establish the minimum cost for cubic space occupied by a package. In fact, UPS and FedEx both announced that from 2015, shipping costs for all shipments (air and surface) would be determined by greater than the actual weight and weight of the packet dimensions. Prior to this announcement, dimensional weight charges apply only to packages with specific size ranges.

Weight calculation
The weight dimension is the theoretical weight calculation of the packet. This theoretical weight is the weight of the packet at the minimum density chosen by the cargo carrier. If the packet is below this minimum density, then the actual weight is irrelevant because the transport carrier will charge for the volume of the packet as if from the selected density (what package will weigh at minimum density). Furthermore, the volume used to calculate the dimensional weight may not actually represent the actual volume of the packet. The cargo transport will measure the longest dimensions in each of the three axes (X, Y, Z) and use this measurement to determine the packet volume. If the packet is a rectangular rectangle (cube-shaped), then this will be equal to the actual volume of the packet. However, if the packet has other forms, then the volume calculation will be more than the actual volume of the packet.
The weight dimension is also known as DIM weight, volumetric weight, or dice weight. Carrier carriers take advantage of greater than actual or dimensional weight dimensions to calculate shipping costs. The weight dimension is calculated as (long ÃÆ'â € "wide ÃÆ'â €" height)/(dimension factor). Measurements can be done in inches or all in centimeters, but appropriate shipping factors should also be used.
The delivery factor for imperial measurements represents cubic inches per pound (in 3 /lb) while the metric factor represents cubic centimeters per kilogram (cm 3 /kg). This is the opposite of packet density. The weight dimension is applied when the actual product density is less than the minimum density represented by the selected factor. The weight dimension is representative of the weight of the packet at minimum density received by the cargo carrier. Shipping factors are not only different for imperial and metric measurements, but also for delivery mode and in some cases between different customers. Shipping factor will be available from shipping carrier. Some common factors are listed below.
Examples of shipping factors of the empire:
- 139 in 3 /lb = 12Ã, lb/ft 3
- 166 in 3 /lb = 10.4 lb/leg 3 - common for IATA delivery
- 194 in 3 /lb = 8.9Ã, lb/ft 3 - common for domestic delivery
- 216 in 3 /lb = 8.0 lb/leg 3
- 225 in 3 /lb = 7.7 lb/leg 3
- 250 in 3 /lb = 6.9 lb/leg 3
Examples of metric delivery factors:
- 5000Ã, cm 3 /kg = 200 kg/m 3
- 6000Ã, cm 3 /kg = 166.667Ã, kg/m 3
- 7000 cm 3 /kg = 142.857 kg/m 3
When calculating the dimensional weight by metric measurement, length, width, and height are measured in centimeters (cm) and the results are expressed in kilograms (kg) of dimension weight (usually rounded up).

Example
By using dimensional weight calculations, the goods carriers will charge for lightweight packets (low density) as if they have a greater weight (packet weight at minimum density received).
For example, an internationally packed 10-pound box of clothes and a size of 18 ÃÆ'â € "18 ÃÆ'â €" 18Ã, "inches will cost as if it weighs 36 pounds: (18 x 18 x 18)/166 = 35.1 pounds then collected up to 36 pounds for the cost of shipping. 35.1 pounds is the packet's 'theoretical' weight if it has a density of 166 in 3 /lb or 10.4 lb/ft 3 : (18 ÃÆ'â € "18 ÃÆ'â € "18) = 3,375Ã, ft 3 ÃÆ'â €" 10.4 lb/leg 3 = 35.1 pounds lb.
Note that for USPS there are two different calculations for the weight of DIM: (L ÃÆ'â € "W ÃÆ'â €" H)/194 for domestic delivery and (L ÃÆ'â € W "H)/166 for international shipments.
Several programs are available for calculating dimensional weight: Measurement Technology DIM Weight Calculator or Dim Weight Calculator
Practical apps
Heavy dimensions support solid body shippers and punish those who send light boxes. A box of unprocessed corn kernels is likely to be charged with gross weight; a box of popcorn may be charged by its dimensional weight. This is because a large box of popcorn takes up a lot of space but does not fill the vehicle's capacity in terms of weight, making it an inefficient use of space.
Shippers avoid the cost of dimensional weight by using smaller boxes, by compressing their goods, and by reducing the use of packing materials.
Commercial use
Dimensions of weight are generally used for invoicing by air carriers, trucks, and all commercial airlines around the world. In 2007, DHL, FedEx, United Parcel Service, and USPS adopted a dimensional weight system for ground services.
In May 2007, the United States Postal Service (USPS) adopted a dimensional weight, calling it "Based on Ship Costs". The tariff system is designed to charge more for light goods, and also to recover costs involving manual sorting and handling, as many post engines are built to handle flats. This system will charge more for sending a packet than a flat envelope. This pushes mailing books and DVDs on flat cardboard or plastic envelopes, rather than soft mailers.
Such companies use automated systems called dimension gauges to calculate actual dimensions and weight and collect their customers accordingly. More and more transport and logistics companies including warehouses and retailers are investing in dimensional equipment to calculate the weight dimensions of their packages to stay in line with their carriers and avoid return costs.
Heavy cubes are used in less than truck delivery (LTL) to fill the trailer with small heavy objects inside with large light objects to increase the load factor. Generally cubes and weights are reference data from delivery tables.
