How to Use the CBM Calculator
Enter box dimensions (L×W×H) and select unit (cm, inches, ft, m). Enter quantity for multiple identical boxes. Get total CBM and volumetric weight for air freight quotes.
CBM Calculator Formula
CBM per box = L(m) × W(m) × H(m); Volumetric weight = CBM × 200 (air freight)Example Calculation
50cm × 40cm × 30cm box, qty 10:
CBM per box = 0.5 × 0.4 × 0.3 = 0.06 m³; Total = 0.6 m³; Vol. weight = 120 kg
Total CBM = 0.6 m³; Volumetric weight = 120 kg
Frequently Asked Questions
What is volumetric weight in shipping?
Volumetric weight = CBM × 200 (standard for air freight). Freight is charged on the higher of actual weight vs volumetric weight. For large but light packages, volumetric weight is often higher.
