Frequently Asked Questions

CBM stands for Cubic Meter — the standard unit for measuring shipping volume. It is calculated as Length × Width × Height (in meters). Freight companies use CBM to determine how much space your cargo occupies in a container.
CBM = Length (m) × Width (m) × Height (m) × Number of Packages. For example, 2 boxes each 0.5m × 0.4m × 0.3m = 0.06 CBM per box × 2 = 0.12 CBM total.
Volumetric (dimensional) weight is a pricing technique used by couriers when the package is light but large. It's calculated as: (L × W × H in cm) / 5000 for air freight, or / 6000 for some couriers. The higher of actual weight and volumetric weight is used for billing.
A 20ft container holds approximately 33 CBM, a 40ft container holds about 67 CBM, and a 40ft High Cube holds about 76 CBM. Actual usable space may be 10-15% less due to packing arrangement and pallet dimensions.
CBM (Cubic Meters) and CFT (Cubic Feet) both measure volume. 1 CBM = 35.3147 CFT. CBM is the international shipping standard. CFT is sometimes used in domestic transport. Our calculator supports both for easy conversion.
