How to calculate CBM: cubic metres of a shipment
CBM (cubic metres) = length × width × height in metres, times the quantity. That is the loading volume of your shipment — the basis for sea freight quotations (LCL) and container utilisation.
The formula
CBM = L (m) × W (m) × H (m) × quantity
Important: all dimensions in metres. Divide centimetres by 100 first (60 cm = 0.6 m).
Example
10 cartons, each 60 × 40 × 40 cm:
| Step | Calculation | Result |
|---|---|---|
| Volume per carton | 0.6 × 0.4 × 0.4 | 0.096 m³ |
| × quantity | 0.096 × 10 | 0.96 CBM |
CBM and freight cost
In sea freight (LCL, groupage) charging usually follows the freight tonne principle: what counts is CBM or weight — whichever is higher (rule of thumb: 1 CBM ≈ 1000 kg). So you need to know both. The 3D calculator shows CBM and weight at the same time and computes container utilisation live.
Enter your packages — the calculator adds up CBM & weight and shows the utilisation in 3D.

No warranty: CBM is the geometric loading volume. Actual freight cost, volumetric weight factors and minimum quantities are set by the carrier or forwarder. The tool calculates purely geometrically and does not replace a binding freight quotation.
