Frequently Asked Questions

How do you calculate CBM from carton dimensions? +

CBM (cubic meters) is calculated by multiplying length, width, and height in meters: CBM = L × W × H. If measurements are in centimeters, divide each by 100 first, or use CBM = (L × W × H in cm) ÷ 1,000,000. Multiply by the carton quantity to get total CBM.

What is the CBM formula used for shipping and freight? +

Total CBM = (L × W × H) × Quantity, with dimensions in meters. In centimeters: Total CBM = (L × W × H × Quantity) ÷ 1,000,000. 1 CBM = 35.3147 ft³ = 1,000 liters. Forwarders use CBM for LCL pricing and container loading.

How many CBM is a 40×40×40 cm carton? +

A 40 × 40 × 40 cm carton equals 0.064 CBM. That’s roughly 2.26 ft³ or 64 liters. Ten cartons of this size would total 0.64 CBM.
