What Is CBM in Shipping and How to Calculate It
3 min read
CBM stands for cubic metre and measures the volume your cargo occupies. It is a key figure in shipping, particularly for less-than-container-load (LCL) freight where you pay for the space you use.
How to calculate CBM
For a box, CBM equals length times width times height, all measured in metres. For example, a carton of 1.2 m x 0.8 m x 0.5 m is 0.48 CBM. Add the CBM of all cartons to get the shipment total.
Why CBM matters for pricing
LCL freight is charged on whichever is greater between weight (per tonne) and volume (per CBM). Light but bulky cargo is usually charged on CBM, while dense cargo may be charged on weight. Knowing your CBM helps you estimate cost and decide between LCL and FCL.
