How to Use Our Free CBM Calculator

Our cubic meter (CBM) calculator makes volume calculations simple for shipping, logistics, and freight purposes. Follow these steps to get accurate results:

1

Choose Your Measurement Unit

Select from Meters, Centimeters, Inches, or Feet. Our CBM Calculator supports multiple units for accurate freight volume calculation.

2

Input Cargo Dimensions

Enter the Length, Width, and Height of your boxes or pallets. Precise dimensions ensure exact CBM calculation for shipping.

3

Set Item Quantity

Input the number of identical packages. Our calculator automatically multiplies volume to give the total shipment CBM.

4

Multi-Item Shipment Support

Use the 'Add Row' feature to calculate total CBM for mixed cargo with different box sizes in a single shipment.

5

Instant CBM Calculation

Get real-time total volume and item count. Perfect for planning container load plans and estimating shipping costs.

6

Analyze & Export Results

View detailed per-item volume and total CBM. Copy data to your clipboard for booking forms or logistics planning.

The calculator automatically converts all measurements to cubic meters (CBM) regardless of which input unit you choose, making it perfect for international shipping calculations.

Understanding CBM in International Shipping

Cubic Meter (CBM) is the standard volume measurement used worldwide in the shipping and logistics industry. Understanding CBM is essential for:

Chargeable vs. Gross Weight

Freight rates are calculated based on whichever is higher: the actual weight or the volumetric weight (derived from CBM). This 'Chargeable Weight' dictates your final shipping cost.

Container Capacity Planning

Knowing your total CBM is crucial for selecting the right container. A 20ft container holds ~33 CBM, while a 40ft container holds ~67 CBM. Optimize space to save money.

Customs & Documentation

Accurate CBM figures are mandatory for Bills of Lading, Packing Lists, and Commercial Invoices. Discrepancies can lead to customs delays or penalties.

Warehousing & Storage

Logistics providers use CBM to calculate storage fees and plan warehouse space. Accurate volume data ensures you only pay for the space you occupy.

Volumetric Weight Conversion Rule

Different transport modes use different density factors. For Air Freight, 1 CBM ≈ 167 kg (1:6000 ratio). For Sea Freight (LCL), 1 CBM ≈ 1000 kg (1:1000 ratio). Always compare actual weight vs. volumetric weight.
