Container figures are volume-only planning estimates: they ignore item fit, pallets, load securing, payload limits, door clearance and carrier-specific equipment. Actual chargeable weight also depends on contract rules.

How to calculate a cubic metre
A cubic metre is the space inside a cube measuring one metre by one metre by one metre. For a rectangular box, volume in m³ equals length (m) × width (m) × height (m). If your dimensions are in centimetres, multiply them and divide by one million. For millimetres, divide the product by one billion.
Example with multiple boxes
A 50 × 40 × 30 cm box uses 0.06 m³. A hundred such boxes occupy 6 m³ by volume, before pallets, gaps and packaging arrangements. Enter quantity and weight per box to see both volume and actual total mass. Multiple rows let you combine differently sized cartons.
When cubic metres are useful
Cubic metres help with warehouse planning, moving quotes, packing-list preparation and sea-freight volume estimates. Cubic capacity is not the same as usable floor space, and an irregular load may leave significant unused gaps. Always check any carrier's specific measurement and rounding instructions.
Frequently asked questions
What is the formula for CBM in centimetres?
Length × width × height ÷ 1,000,000 gives m³ for dimensions in centimetres.
Does a cubic metre tell me the weight?
No. Volume and mass are distinct measurements; enter actual weight separately.
