Procedure

How to use this tool

01
Enter outside dimensions for one piece and the total piece count.
02
Enter the shipment’s total actual scale weight.
03
Select the exact divisor and unit system used by the carrier, then compare both weights.

Useful for

Common planning tasks

Pre-rating air freight
Parcel shipment checks
Packaging optimization

Model boundary

Assumptions

All pieces are identical.
Actual weight is the total for all pieces.
Chargeable weight is the greater of total actual and total dimensional weight.

Operational caution

Limitations

Carrier minimums, shipment-level rounding, oversize rules, and density breaks are excluded.
Published divisors can differ by carrier, lane, product, and contract.

Reference

Questions and answers

What is dimensional weight?

It is a rating weight derived from package volume divided by a carrier-defined volumetric divisor.

Which divisor should I choose?

Use the divisor in your carrier tariff, contract, or current service guide; do not assume one is universal.

Is this a freight quote?

No. It estimates rating weight only and does not apply rates, minimums, surcharges, or taxes.
