How CBM is calculated
How it works
Use this local planning estimate to compare axis-aligned package dimensions and declared quantities. Calculation rules, units, limits, orientations, and rounding remain code-owned.
Formula and units
Formula and decision logic
For each package row, convert dimensions to metres, then calculate length × width × height × quantity. Add every valid row.
Units and rounding
Dimensions accept cm or in. Volume is shown to three decimal places in m³ and two decimal places in ft³; weight is shown to one decimal place.
Assumptions
- Inputs describe regular rectangular packages and planning dimensions.
