CBM calculator

Enter how many packages you have of each size. The calculator adds up the volume in cubic metres (CBM) and cubic feet, and shows roughly how much of a container it would fill.

Total volume of 10 packages

1.200 m³

42.4 cubic feet

20′ standard

About 28 m³ loadable (33.2 m³ inside)

Fills about 4%

40′ standard

About 58 m³ loadable (67.7 m³ inside)

Fills about 2%

40′ high cube

About 68 m³ loadable (76.3 m³ inside)

Fills about 2%

A rough guide: what really fits depends on the packing, pallets and the container’s weight limit.

How to calculate CBM

CBM = length × width × height (in metres) × number of packages. With sizes in centimetres, divide length × width × height by 1,000,000 first. In inches, divide by 61,024.

Example: 10 cartons of 60 × 40 × 50 cm are 0.6 × 0.4 × 0.5 = 0.12 m³ each, 1.2 CBM in all, or about 42.4 cubic feet.

How much fits in a container

A container never fills completely: package shapes, pallets, gaps and the weight limit take space. As a rough guide you can load about 28 m³ into a 20′, 58 m³ into a 40′ and 68 m³ into a 40′ high cube, a little less with pallets or awkward cartons.

Questions

CBM means cubic metre (m³), the unit of cargo volume in shipping. One CBM is a box 1 m long, 1 m wide and 1 m high. Sea LCL rates, warehouse storage and container planning are all based on it.
