Many LCL quotations use weight or measure, often written W/M, to determine the revenue quantity. This calculator compares shipment cubic metres with weight in metric tonnes.
How to use this calculator
Enter shipment CBM and gross kilograms. The tool converts kilograms to metric tonnes and selects the greater figure as the W/M planning quantity.
Formula and method
W/M revenue units equal the greater of shipment CBM or shipment weight in metric tonnes under the common one-CBM-versus-one-tonne planning convention.
Worked example
An 8 m³ shipment weighing 2,500 kg compares 8 CBM with 2.5 tonnes, so the volume side controls and the planning revenue quantity is 8 W/M.
What to check before you ship
Quote structures can vary by forwarder, lane and charge type. Confirm how the specific charge on your quote defines weight, measure, minimums and rounding.
Why the result matters
Accurate dimensions and weights help with quoting, space planning and avoiding preventable adjustments. Always use the packaged outside dimensions that will actually be tendered for transport, and verify any carrier-specific rules that affect billing or classification.
