Formula
CBM = L × W × H ÷ 1,000,000 in centimeters.
Cartons that fit = container CBM ÷ one carton, rounded down. Total CBM = one carton times the count. The container volumes are planning figures, not a steamship line's current card.

CBM calculator for cartons and a container
This CBM calculator turns a carton into cubic meters and multiplies by the count. The container loading calculator and shipping container calculator lines use planning volumes: 33.2 CBM for a 20 foot box, 67.7 for a 40, and 76.3 for a 40 foot high cube. Those are volume limits, not a stowage plan.

Planning estimate from the numbers you enter. Coverage, density, waste and price are assumptions, not a supplier quote or an engineering specification.
How it works
One CBM is a cube one meter on a side.
In centimeters, CBM is length times width times height divided by 1,000,000. In inches, divide the cubic inches by 61,023.744. A 120 by 100 by 80 centimeter carton is 0.960 CBM. Ten of them are 9.600 CBM. A 20 foot container at 33.2 CBM holds 34 of those cartons by volume, because 33.2 divided by 0.960 is 34.58 and the fraction does not ship. Weight, door height, and bracing can cut that number. This shipping container calculator does not check payload or axle limits.

Example
120 × 100 × 80 cm, ten cartons, a 20 foot box.
Each carton is 0.960 CBM. The shipment is 9.600 CBM. Volume says 34 cartons fit in 33.2 CBM. If the cartons are heavier than the container's payload allows, volume is the wrong limit. Weigh them.

Tips
Cubic meters ignore the gaps.
A carton that is almost as wide as the container may leave a strip you cannot fill. Round down again when you know the carton will not tile. High-cube height only helps if the cartons can stack to it.

Equipment
Loading is forklift work.
Dengaro arranges financing for a forklift or a pallet jack. The CBM total is not a loan amount.
Important questions
Know what to expect.
What is a CBM in inches?+
Multiply the three inch dimensions and divide by 61,023.744. Switch the unit control to inches and type the inch edges. Do not mix centimeters and inches in one measurement.
Are 33.2, 67.7, and 76.3 exact container sizes?+
They are common internal volume figures used for planning. A specific box can differ. The container loading calculator is a volume check, not a booking.
Does the shipping container calculator include weight?+
No. It divides container volume by carton volume. A heavy carton can hit the payload before it hits the cube. Check the weight separately.
Why round the fit down?+
You cannot load a fraction of a carton. 34.58 becomes 34. If the last row will not fit through the door, the real count is lower still.
