Why These Logistics Tools Matter
Dimensional weight matters because carriers often charge based on the greater of actual weight or dimensional weight. Freight class matters because LTL pricing is influenced by density, handling, stowability, and liability. Unit conversions matter because logistics teams, freight forwarders, airlines, ocean carriers, and international suppliers often use different measurement systems.

What is freight class?
Freight class is an LTL shipping category influenced by density, handling, stowability, and liability. This calculator estimates class based on density only.
What is CBM in ocean freight?
CBM means cubic meter. Ocean freight often uses CBM to measure cargo volume, especially for LCL shipments.
Can I enter multiple boxes?
