CBM Calculator Overview

CBM (Cubic Meter) is used to calculate the volume of cargo, which helps determine shipping cost and container/airspace utilization.

For Sea Freight (FCL / LCL):

CBM=Length (m)×Width (m)×Height (m)

• Dimensions must be in meters.
• Example: 2m × 1.5m × 1.2m = 3.6 CBM

For Air Freight (Volumetric Weight): Air cargo uses volumetric weight, which converts CBM to kg:

Volumetric Weight (kg)=Length (cm)×Width (cm)×Height (cm)/6000

• Dimensions in cm, divide by 6000 (IATA standard)
• Example: 120cm × 80cm × 60cm → 120×80×60/ 6000=96kg

Airlines charge whichever is higher: actual weight or volumetric weight.
