Formula and measurement method
Volumetric kg = length × width × height (cm) × quantity ÷ divisor.
Use the outside dimensions of the packed carton or pallet, not the product dimensions before packing. Round and rating rules can differ by airline, service and contract.
- Measure the packed outer length, width and height in centimetres.
- Multiply by the number of identical packages and divide by the selected planning divisor.
- Compare the result with actual gross weight; use the larger figure as the planning chargeable-weight reference.
Worked examples
- 60 × 40 × 50 cm × 2; gross 28 kg → ÷6000 = 40 kg; ÷5000 = 48 kg; Planning chargeable weight: 40 / 48 kg*
- 40 × 30 × 30 cm × 5; gross 40 kg → ÷6000 = 30 kg; ÷5000 = 36 kg; Planning chargeable weight: 40 kg*
* The applicable divisor and rounding rule must be confirmed with the live carrier/service.
6000 vs 5000: which divisor should I use?
6000 and 5000 are both common planning references in international air cargo and courier contexts, but there is no single divisor that is correct for every airline, product or contract.
Use the calculator to compare scenarios, then confirm the actual rating rule when requesting the live shipment quote.
What to send with the calculator result
A calculator result is useful only when it is tied to the real shipment. Send the packed measurements together with these details:
- Origin city/airport or pickup address and destination airport/final postcode.
- Product name, packaging, pieces and total gross weight.
- Cargo-ready date, required arrival timing and Incoterms.
- Packing list or carton/pallet dimensions when available.
