How CBM is calculated
- CBM (m³) = (Length × Width × Height in cm) ÷ 1,000,000, multiplied by quantity.
- Cubic Feet (ft³) = CBM × 35.3147.
- CBM is the standard chargeable unit for LCL ocean freight (1 CBM ≈ 1,000 kg). For air freight, the volumetric weight uses a divisor of 6,000 (express couriers use 5,000).
- Always measure the OUTSIDE of the carton (incl. corner protectors) — carriers measure to the largest point.
- ⚠ Pallets, slip-sheets, and overhang are part of the chargeable volume — a 1m×1m×1.2m pallet of cartons = 1.2 CBM, not the carton stack volume.
Estimates only — final pricing depends on actual cargo, route, season, and carrier capacity. Get a binding quote before committing.

How to calculate CBM from packed cartons
- Measure the outside length, width and height of one packed carton.
- Select the measurement unit and enter the number of identical cartons.
- Calculate different carton sizes separately, then add their volumes. Include pallets and protective packaging where used.
Example and interpretation
10 cartons × 60 cm × 40 cm × 50 cm ÷ 1,000,000 = 1.2 CBM. One carton is 0.12 CBM. Use packed dimensions rather than the product dimensions inside the carton.
Before you rely on the result
CBM is physical volume, not a guaranteed billable quantity. Freight minimums, density rules, non-stackable cargo and service conditions can change the quantity charged.
