6.00 kgDimensional weight 6.00 kg vs actual 5.00 kg; divisor 4,000. Dimensional weight applies.
Inputs
- Carrier divisor
- Australia Post / StarTrack divide by 4,000
- Length
- 40 cm
- Width
- 30 cm
- Height
- 20 cm
- Actual weight
- 5 kg
Method
Dimensional weight = length cm x width cm x height cm / carrier divisor. Chargeable weight = max(dimensional weight, actual weight).
- 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.
Assumptions
- This calculator is for planning and education, not legal, tax, medical, immigration, engineering or financial advice.
- Use current official rates, contracts, carrier terms, statutes or professional guidance before relying on the result.
- The default values are examples. Replace them with the figures from the job, invoice, contract, bill, service or record being checked.
Notes

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.

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.Master's Tip

Questions
What is the Dimensional Weight Calculator?
Dimensional weight compares parcel volume against actual scale weight so freight quotes charge the larger of volumetric weight and actual weight.
Can I rely on this as professional advice?
No. Use it as a transparent planning estimate, then verify the current rule, rate, contract or official source for the decision you are making.
