60 × 50 × 40 ÷ 6000 = 20.00 kg
What is the calculation telling you?
The example carton measures 60 × 50 × 40 cm outside its packing: 120,000 cm³, or 0.12 m³. At an illustrative divisor of 6,000, its volumetric weight is 20 kg. If the packed carton actually weighs 8 kg, the higher comparison figure is 20 kg before any tariff adjustments.
| Actual weight | Divisor | Volumetric weight | Higher comparison weight |
|---|---|---|---|
| 8 kg | 6,000 cm³/kg | 20 kg | 20 kg |
| 8 kg | 5,000 cm³/kg | 24 kg | 24 kg |
| 28 kg | 6,000 cm³/kg | 20 kg | 28 kg |
Changing the divisor changes the comparison. A heavier item can instead be rated on actual weight. Use the divisor in your written quotation rather than assuming every air or courier service uses the same one.
DHL Aviation explains the actual-versus-volumetric comparison. The scenarios here illustrate the arithmetic; they are not carrier quotations.
Which measurements belong in the quote?
Measure the packed outside dimensions and include the packaging in the actual weight. Ask whether the carrier measures each piece individually and how it handles rounding, pallets, overhang or non-stackable pieces.
A smaller protective package can change the volume, but reducing protection to save space can create another problem. Agree a suitable packing method for the item before treating the estimate as final.
When might air complement a sea shipment?
Separate belongings by when you need them rather than assuming the whole home needs one transport method. Identify a small group of arrival essentials and compare the complete air service with carrying suitable items yourself.
If the move is split between consignments, coordinate the inventories and destination documentation before dispatch. Acceptance, customs arrangements and any relief eligibility require a destination-specific check. Batteries, liquids and other potentially restricted contents must be declared for assessment; this calculator does not determine whether an item can fly.
What does the calculator leave out?
A chargeable weight is not a door-to-door price. Packing, collection, handling, security, clearance work, destination delivery, minimum charges and other tariff conditions can affect the final quotation.
Ask for the actual weight, dimensions, divisor and charging scope together. For multiple packages, request the carrier’s calculation for the complete consignment rather than multiplying this single-carton example without checking the rating method.
