CBM to Cubic Feet (and Cubic Feet to CBM)
One cubic metre (1 CBM) is 35.3147 cubic feet. To convert CBM to cubic feet, multiply by 35.3147; to convert cubic feet to CBM, divide by 35.3147. The tables below give the common shipping volumes both ways.
The formula
Cubic feet = CBM × 35.3147
CBM = cubic feet ÷ 35.3147 (the same as cubic feet × 0.0283168)
The factor comes from the foot itself: one foot is exactly 0.3048 m, so one cubic foot is 0.3048 × 0.3048 × 0.3048 = 0.0283168 m³, and one cubic metre is 1 ÷ 0.0283168 = 35.3147 ft³.

Worked examples
12.5 CBM in cubic feet. 12.5 × 35.3147 = 441.43 ft³.
600 cubic feet in CBM. 600 ÷ 35.3147 = 16.990 m³.
A carton measured in inches. 24 × 16 × 12 in = 4,608 cubic inches. Divide by 1,728 for cubic feet: 2.667 ft³. Divide that by 35.3147 for CBM: 0.0755 m³.
Common questions
Is CBM the same as cubic metres?
Yes. CBM stands for cubic metre (m³). Freight forwarders use CBM; it is the same unit.
Is CFT the same as cubic feet?
Yes. CFT, cu ft and ft³ all mean cubic feet.
How many cubic feet is 1 CBM?
35.3147 cubic feet (35.31 is close enough for a quotation).
How many CBM is 1 cubic foot?
0.0283 m³.
