How to Calculate CBM and Weight for Multiple Packages

Meta Description:
Learn how to calculate CBM and chargeable weight for multiple boxes with different sizes and weights. Step-by-step examples for exporters by Singh International Xpress, Amritsar.

📦 Understanding CBM and Weight

CBM (Cubic Meter) measures volume:
CBM = Length × Width × Height (in meters)

Volumetric Weight (Air Cargo):
Volumetric Weight (kg) = (Length × Width × Height in cm) ÷ 5000

Sea Cargo Approximation:
1 CBM ≈ 1000 kg

Chargeable weight = higher of actual weight or volumetric weight.

⚖️ Example: Multiple Boxes with Different Sizes & Weights

Explanation

1. Box 1 (0.5 CBM, 800 kg)

   • Sea cargo volumetric weight = 0.5 × 1000 = 500 kg

   • Actual weight = 800 kg → Chargeable weight = 800 kg

2. Box 2 (5 CBM, 500 kg)

   • Sea cargo volumetric weight = 5 × 1000 = 5000 kg

   • Actual weight = 500 kg → Chargeable weight = 5000 kg

3. Box 3 (1 CBM, 200 kg)

   • Volumetric weight = 1 × 1000 = 1000 kg

   • Actual weight = 200 kg → Chargeable weight = 1000 kg

4. Box 4 (2 CBM, 1800 kg)

   • Volumetric weight = 2 × 1000 = 2000 kg

   • Actual weight = 1800 kg → Chargeable weight = 2000 kg

✅ Key Point: Always charge based on the higher weight (actual or volumetric).

📝 Tips for Exporters with Multiple Boxes

• Measure each box separately for CBM and weight.

• Sum up CBM for container loading.

• Sum up chargeable weights to estimate shipping cost.

• Use packing software or Excel for multiple packages.

• For irregular shapes, approximate dimensions carefully.
