wikiHow Volumetric Weight Calculator Volumetric weight (also known as dimensional weight) is a calculation used by shipping companies to determine the shipping cost based on the size of the package. It is calculated by comparing the actual weight of the package to its volume or size. The formula for calculating volumetric weight is: Volumetric Weight (kg) = (Length x Width x Height) / Volumetric Conversion Factor The volumetric conversion factor varies depending on the unit of measurement used for the package's dimensions. For example, if the dimensions are measured in centimeters, the conversion factor is typically 5,000. If the dimensions are measured in inches, the conversion factor is typically 139. Here is an example of how to calculate volumetric weight: Suppose you need to ship a package that measures 50 cm x 40 cm x 30 cm and weighs 10 kg. Calculate the package's volume by multiplying its length, width, and height: 50 cm x 40 cm x 30 cm = 60,000 cubic centimeters (cc) Divide the package's volume by the volumetric conversion factor: 60,000 cc / 5,000 = 12 kg Compare the actual weight of the package to its volumetric weight: 10 kg vs 12 kg The shipping company will typically charge based on the higher of the two weights, which in this case is 12 kg. It's important to note that the specific volumetric conversion factor used may vary depending on the shipping company and the country or region where the package is being shipped. Additionally, some shipping companies may use different formulas or methods for calculating volumetric weight. Page
