12. Understanding Volumetric Weight and Its Conversion
What is Volumetric Weight?
Volumetric weight, also known as dimensional weight, is a pricing technique used by commercial freight and courier services (such as FedEx, UPS, DHL) that uses an estimated weight calculated from the length, width, and height of a package. This ensures that shippers are charged based on the space a package occupies, rather than just its actual weight.
Why is Volumetric Weight Important?
Carriers use volumetric weight to account for the density of packages. If a package is lightweight but takes up a lot of space, it can still impact the carrier’s capacity. Volumetric weight helps carriers optimize their space and recover costs.
How to Calculate Volumetric Weight
The formula for calculating volumetric weight varies depending on the carrier but generally follows this pattern:
Volumetric Weight = (Length × Width × Height) / Volume Division Factor
- Length, Width, and Height are measured in inches or centimeters.
- The Volume Division Factor (also known as DIM factor or divisor) is a number specified by the carrier.
Converting Volumetric Weight from Pounds to Kilograms
After calculating the volumetric weight in pounds, you can convert it to kilograms using the standard conversion factor:
Volumetric Weight (kg) = Volumetric Weight (lb) × 0.45359237
Example Calculation
Let’s say you have a package with the following dimensions:
- Length = 20 inches
- Width = 15 inches
- Height = 10 inches
- Volume Division Factor = 139 (a common factor used by some carriers)
First, calculate the volumetric weight in pounds:
Volumetric Weight (lb) = (20 × 15 × 10) / 139 = 21.58 lb
Now, convert this to kilograms:
Volumetric Weight (kg) = 21.58 lb × 0.45359237 = 9.79 kg
So, the volumetric weight of the package is approximately 9.79 kg.
Practical Tips for Reducing Volumetric Weight
- Use appropriately sized packaging: Avoid oversized boxes that create unnecessary space.
- Compress contents: If possible, compress items to reduce the overall dimensions of the package.
- Choose the right carrier: Different carriers use different volume division factors, so compare rates and factors to find the most cost-effective option.
