Sea Freight CBM Calculator

Calculate cubic meters (CBM) for ocean freight shipments and plan LCL and FCL container loads.

Ocean freight volume is measured in cubic meters. CBM = length × width × height in meters. For LCL, carriers commonly compare volume against weight using a ratio of 1 CBM to 1,000 kg and charge whichever is greater.

How to use the Sea Freight CBM Calculator

  • Enter the dimensions and quantity of each carton or pallet.
  • Review the total CBM.
  • Compare the result with LCL pricing and container capacity before booking.

Frequently asked questions

How do I calculate CBM?

Multiply length × width × height in meters, then multiply by the number of packages.

What is the weight-to-volume ratio in LCL?

A common ratio is 1 CBM = 1,000 kg. Cargo heavier than that per CBM may be charged by weight.
