Volumetric weight (also called dimensional weight) calculates the density of a package and helps determine chargeable weight when a shipment occupies more space than its actual weight.
If your shipment has a large volume but low actual weight, it's considered volumetric or bubble cargo, meaning shipping cost is based on volume rather than physical weight.
Use a volumetric weight calculator. If the volumetric weight exceeds the actual weight, your cargo is bubble cargo and may incur higher charges.
Measure the length, width, and height of the package in centimeters (or inches if supported), rounding up to the nearest whole number for accuracy.
Actual weight is the measured weight on a scale, while volumetric weight is calculated from package dimensions. Shipping charges are based on whichever is higher.
Chargeable weight is the greater value between actual weight and volumetric weight. It determines the cost you pay to ship your package.
The standard formula is: (Length × Width × Height in cm) ÷ 6000. For inches, divide cubic inches by 366. This calculator uses 6000 as the default divisor, following most airline standards.
For a package measuring 50cm × 40cm × 30cm: (50 × 40 × 30) ÷ 6000 = 10 kg volumetric weight.
IATA recommends charging based on the greater of actual weight or volumetric weight, with the divisor 6000 for volumetric weight in air freight.
Yes. While 6000 is common, some carriers use 5000 or 4000. Always check with your freight forwarder or airline for exact divisors.
The dim factor is the divisor used to calculate volumetric weight, commonly 6000, 5000, or 4000 depending on the carrier.
Some carriers updated dimensional factors and chargeable weight policies in 2025. Stay updated by consulting your carrier or logistics provider.
Multiply CBM by 167 to estimate chargeable weight in kilograms. For example, 1 CBM × 167 = 167 kg.
Use (L × W × H in inches) ÷ 366 to get dimensional weight in pounds, then convert to kilograms by dividing by 2.2046.
Input your package's length, width, height (in cm) and actual weight (in kg). The tool will calculate both volumetric and chargeable weights automatically.
Currently, the calculator supports centimeters and kilograms. For inches or pounds, convert measurements to cm/kg before using the tool.
Yes. If volumetric weight exceeds actual weight, the calculator estimates how much you might save by optimizing your package size.
This calculator uses the standard 6000 divisor most airlines use. DHL and FedEx sometimes use 5000, so check your carrier's rules for exact calculations.
No, this tool is specifically designed for air freight volumetric weight calculations.
No. All calculations are done locally in your browser, and no data is stored or collected.
Reduce package dimensions, use denser packing materials, and eliminate empty spaces to lower volumetric weight charges.
Yes, by repacking your shipment efficiently and increasing density. Avoid misdeclaring weight or dimensions as this is illegal and risky.
If volumetric weight is significantly higher than actual weight, especially with lightweight items, repacking may save considerable costs.
Absolutely. Even small reductions in dimensions can noticeably lower volumetric weight and shipping fees.
Savings vary by carrier rates and packaging improvements. The tool gives you instant projections based on your inputs.
Yes, it's advisable to discuss final rates and optimization options with your logistics provider.
