What is CBM?
A cubic meter (CBM) represents the volume of cargo, calculated by multiplying length x width x height in meters. This standard measurement helps determine how much space shipments occupy in containers or vessels. One CBM equals one cubic meter of space, regardless of the cargo's weight.
How to Calculate CBM
Understanding CBM calculation is essential:
- Convert all measurements to meters
- Multiply length x width x height
- Round up to three decimal places
- Account for packaging dimensions
- Include pallets if used
- Consider irregular shapes carefully
- Formula: CBM = Length (m) × Width (m) × Height (m)
Why CBM Matters in Shipping
CBM impacts several shipping decisions:
- Determines freight costs for LCL shipments
- Helps plan container loading
- Affects carrier quotes and charges
- Influences mode of transport selection
- Guides warehouse space planning
- Essential for comparing carrier rates
Always measure cargo carefully and include packaging dimensions in CBM calculations. For irregular shapes, calculate the total volume of the smallest rectangular box that would contain the item. Keep in mind that carriers typically charge based on either actual weight or volume weight (CBM), whichever is greater.
