Formula

CBM per carton = L × W × H (cm) ÷ 1,000,000. Total CBM = per-carton CBM × cartons. Total pieces = pieces per carton × cartons. 20ft fill % = total CBM ÷ 28 × 100 (20ft ≈ 28 usable CBM; 40ft ≈ 58 CBM).

Worked example

A 60 × 40 × 40 cm carton = 0.096 CBM holding 50 shirts. A 20-carton shipment = 1.92 CBM with 1,000 pieces, filling just 6.9% of a 20ft container — clearly an LCL shipment. A 200-carton order = 19.2 CBM (68.6% of a 20ft), worth pricing as a full container versus LCL.
