Formula
Dimensional weight = length cm x width cm x height cm / carrier divisor. Chargeable weight = max(dimensional weight, actual weight).
Worked example
A 40 cm x 30 cm x 20 cm parcel with a 4,000 divisor has dimensional weight of 6 kg. If actual weight is 5 kg, the chargeable weight is 6 kg.

Methodology & Accuracy
How this calculator is checked
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.
Formula used
Dimensional weight = length cm x width cm x height cm / carrier divisor. Chargeable weight = max(dimensional weight, actual weight).
Standard or basis
Carrier divisor defaults: Australia Post and StarTrack commonly use 4,000; FedEx, DHL and UPS examples use 5,000. Confirm the current service guide before booking.
Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.
