CBM calculator for cartons and containers
To calculate CBM, multiply a carton's length, width and height in metres, then multiply by the number of cartons. Enter your cartons below to get total CBM, weight, sea and air billing figures, and how much of a container you will use.
CBM formula
CBM = length (m) × width (m) × height (m) × number of cartons. For example, 120 cartons of 60 × 40 × 40 cm: 0.6 × 0.4 × 0.4 = 0.096 m³ per carton, so 11.52 m³ in total.
| Measured in | Formula for one carton |
|---|---|
| Centimetres | L × W × H ÷ 1,000,000 |
| Millimetres | L × W × H ÷ 1,000,000,000 |
| Inches | L × W × H ÷ 61,024 |
| Feet | L × W × H ÷ 35.315 |
How much fits in a container?
Nominal volume is not usable volume. A 40HQ holds about 76 m³, but about 66 m³ is a realistic carton load. See container dimensions for each type.
CBM only tells you volume. To check whether your cartons actually fit, try the container loading calculator, which works out rows, columns and layers.
