CBM (Cubic Meter) is the foundation of sea freight pricing, especially for LCL shipments. Miscalculating CBM leads to incorrect quotes, unexpected charges, and booking issues.
📍 DisMove, operating from Guangzhou, ensures accurate CBM calculation and space optimization so you pay only for what you actually ship.
📦 What Is CBM?
📐 CBM (Cubic Meter) measures the volume of cargo, calculated as:
📏 Length × Width × Height (in meters)
CBM is used to:
💰 Price LCL shipments
📦 Plan container loading
⚖️ Compare volume vs weight
🚢 Optimize FCL utilization
🧮 Basic CBM Formula
📐 Single Carton
CBM = Length (m) × Width (m) × Height (m)
📦 Example:
0.6 m × 0.4 m × 0.5 m = 0.12 CBM
📦 Multiple Cartons
Total CBM = CBM per carton × Number of cartons
📦 Example:
0.12 CBM × 50 cartons = 6 CBM
📏 Using Centimeters (Most Common Mistake)
If dimensions are in centimeters, convert to meters:
📐 Formula
CBM = (L × W × H in cm) ÷ 1,000,000
📦 Example:
60 × 40 × 50 cm = 120,000 ÷ 1,000,000 = 0.12 CBM
⚖️ CBM vs Weight — Which One Matters?
Sea freight uses:
📦 CBM (volume)
⚖️ Gross weight
⚖️ Heavy Cargo
- Low CBM
- Weight matters more
📦 Light but Bulky Cargo
- High CBM
- Volume determines cost
DisMove compares both to select FCL or LCL.
🚢 CBM in LCL vs FCL Shipping
📦 LCL
💰 Charged per CBM
📦 Minimum charge often 1 CBM
🚢 FCL
💰 Container price is fixed
📦 CBM used for optimization, not pricing
CBM helps decide when to switch to FCL.
📊 Typical Container CBM Capacity
| 📦 Container | Approx. CBM |
|---|---|
| 20ft (20GP) | ~33 CBM |
| 40ft (40GP) | ~67 CBM |
| 40ft High Cube (40HC) | ~76 CBM |
⚠️ Actual usable CBM depends on cargo shape & packaging.
⚠️ Common CBM Calculation Mistakes
🚫 Forgetting pallet height
🚫 Using internal box size instead of packed size
🚫 Ignoring overhang
🚫 Rounding down incorrectly
🚫 Mixing units (cm vs m)
These mistakes cause re-quoting and delays.
