To calculate CBM for sea freight from China to Canada, multiply the packed length × width × height of the cargo in metres, then multiply by the number of identical packages. CBM stands for cubic metre and represents the amount of physical space a shipment occupies.

Sea Freight CBM & LCL W/M Calculator

Calculate total shipment volume, gross weight and the planning W/M value commonly used for LCL sea freight. Add separate rows for cartons, pallets or crates with different dimensions.

CBM formula L × W × H × Qty
For planning: CBM measures volume. In many LCL quotations, volume in CBM is compared with gross weight in metric tons (1,000 kg); the higher W/M value may be used for rating. Always confirm the actual tariff and minimum charges on your freight quote.

CBM is one input only. Final LCL/FCL selection also depends on weight, density, cargo handling, current rates and destination charges.

20ft~33 CBM nominal
40ft~67–68 CBM nominal
40HQ~76 CBM nominal

Important: This calculator is a planning tool, not a carrier tariff or freight quotation. Actual chargeable W/M, minimums, density rules, dimensions and fees can vary by consolidator, carrier, route and service.

The basic formula is:

CBM = Length (m) × Width (m) × Height (m) × Quantity

If your supplier provides carton dimensions in centimetres, use:

CBM = Length (cm) × Width (cm) × Height (cm) × Quantity ÷ 1,000,000

For example, ten cartons measuring 60 × 50 × 40 cm equal 1.20 CBM:

60 × 50 × 40 × 10 ÷ 1,000,000 = 1.20 CBM
