CBM Cargo Volume Calculator
Calculate the cubic meter (CBM) volume and dimensional specifications of your commercial cargo shipments instantly.
Multi-Package Cargo Specification
Add distinct carton types, skids, or crates to aggregate consolidated shipment volume.
Volumetric Weight Conversion References
Standard IATA formula: 1 CBM ≈ 167 kg chargeable volumetric weight. Air carriers bill by whichever is greater: actual gross weight or volumetric weight.
Standard ocean W/M (Weight or Measure) convention. LCL ocean shipments are charged on whichever yields the higher rate (1 MT or 1 CBM).
CBM is an estimate of cargo volume and does not represent a confirmed freight charge. Actual shipping costs depend on shipment specifications, route, chargeable weight, and applicable carrier or service-provider rates.

Standard Pallet Optimization
Standard Euro pallets (120×80 cm) and ISO standard pallets (120×100 cm) necessitate precise stack height checks to prevent overhead vessel or air-deck overhang penalties.
Irregular & Bulky Cargo
For non-standard crates or cylindrical drums, always measure according to the outermost extreme bounding box points (Length × Width × Height) to reflect carrier chargeable space.
FCL vs LCL Consolidation
Shipments exceeding 15 CBM are typically evaluated for exclusive Full Container Load (FCL) bookings, whereas lesser volumes benefit from consolidated Less than Container Load (LCL).
CBM Frequently Asked Questions
Essential information regarding dimensional volume, carrier ratings, and container allocation.
Freight charges across air and ocean logistics are determined by whichever takes up more operational carrier capacity: the physical weight (Gross Weight) or the space it occupies (Volumetric Weight):
- Ocean Freight (LCL): Carriers charge on a "Weight or Measurement" (W/M) basis where 1 CBM = 1,000 kg (1 Metric Ton). If your cargo measures 3 CBM but weighs only 500 kg, you are billed for 3 "Revenue Tons" based on volume.
- Air Freight: Space on aircraft is strictly constrained, using a dimensional weight ratio of 1:6000 (1 CBM ≈ 167 kg). If a 1 CBM carton weighs 80 kg physically, air carriers bill at 167 kg chargeable weight.
Chargeable Weight is the billable metric used on carrier air waybills and ocean bills of lading. It is mathematically established as the greater value between the Gross Weight and the Dimensional (Volumetric) Weight. For lightweight, bulky cargo (like pillows, optics, or garments), the chargeable weight is almost always determined by your total calculated CBM.
