Cubic Centimetres and Cubic Inches to CBM
One CBM (cubic metre) is 1,000,000 cubic centimetres and 61,023.7 cubic inches. To get CBM from a carton measured in centimetres, multiply length × width × height and divide by 1,000,000. For inches, divide by 61,023.7.
The formulas
From centimetres: CBM = length × width × height (cm) ÷ 1,000,000
From millimetres: CBM = length × width × height (mm) ÷ 1,000,000,000
From inches: CBM = length × width × height (in) ÷ 61,023.7
From feet: CBM = length × width × height (ft) ÷ 35.3147
One inch is exactly 2.54 cm, so one cubic inch is 2.54 × 2.54 × 2.54 = 16.387 cm³, and 1,000,000 ÷ 16.387 = 61,023.7 cubic inches in a cubic metre.

1,728 in³ is one cubic foot. 4,608 in³ is a 24 × 16 × 12 in carton.
Worked examples
Carton 60 × 40 × 30 cm. 60 × 40 × 30 = 72,000 cm³. 72,000 ÷ 1,000,000 = 0.072 CBM. For 500 cartons: 0.072 × 500 = 36 CBM.
Carton 24 × 16 × 12 in. 24 × 16 × 12 = 4,608 in³. 4,608 ÷ 61,023.7 = 0.0755 CBM. For 500 cartons: 37.76 CBM.
Carton 600 × 400 × 300 mm. 600 × 400 × 300 = 72,000,000 mm³. Divide by 1,000,000,000: 0.072 CBM.
Common questions
Why divide by 1,000,000 for centimetres?
A metre is 100 cm, so a cubic metre is 100 × 100 × 100 = 1,000,000 cm³.
Should I measure the product or the carton?
The outside of the packed carton, at its widest points. Freight is charged on the space the carton takes, including any bulge.
How many litres is 1 CBM?
1,000 litres.
Next step
Enter carton sizes in cm, mm, m or inches with quantities: it totals the CBM and cubic feet, checks the weight and shows what fits a 20ft, 40ft or 40ft High Cube container.
