Frequently asked questions

What is volumetric weight?

Volumetric weight converts package dimensions into an equivalent weight so low-density shipments can be priced by the space they occupy.

What divisor should I use?

Common divisors include 5000 and 6000 for centimetres and kilograms, but the correct value depends on the carrier and service.

What is chargeable weight?

Chargeable weight is commonly the greater of actual weight and volumetric weight.

Does every courier use the same formula?

No. Confirm the divisor, rounding and minimum charge rules with the selected carrier.
