Compare gross weight with volumetric weight using the selected divisor. The higher value generally controls the estimate.

CBM calculator
Calculate shipment volume, gross weight, air freight volumetric weight, and estimated chargeable weight across multiple package types.

Waiting for dimensions
Enter at least one complete item to see which weight controls the estimate.

Mode decision
Use the same dimensions to answer three freight questions.
The calculator gives a planning estimate. Senate Freight then checks aircraft contour, container fit, route minimums, carrier rounding, and special-handling rules before confirming a quote.
Use cubic metres to plan consolidation, handling, and shipment density before final rate confirmation.
Use CBM only as a starting point, then compare actual package dimensions with container door, internal height, and loading method.
How calculations work
Volume and weight answer different questions.
CBM shows physical volume. Air freight commonly compares actual gross weight with volumetric weight and charges the higher value.
L × W × H × quantity ÷ 1,000,000Use centimetres to calculate cubic metres.
L × W × H × quantity ÷ selected divisorChoose 6,000 for common air-freight planning or 5,000 when required by an express or specific carrier rule.
Unit weight × quantityEnter the packed weight of one piece.
Higher of volumetric or gross weightThe final airline calculation may use a different divisor or rounding method.
Estimate only
Carrier rules, mode, route, minimum charges, density, rounding, pallet contours, and special handling can change the chargeable weight. For sea freight, CBM supports LCL planning but does not confirm container fit or freight price.
