How parcel volume is calculated
Multiply length × width × height using one measurement unit. The calculator converts the result to cubic metres (CBM), litres and cubic feet. Measure the packed parcel on the outside and use the same unit for all three sides.
When to use a CBM estimate
CBM is useful for planning storage and freight space. It is not a shipping quote: each carrier or freight service can apply its own dimensional-weight divisor, minimums, rounding and package rules.
For a parcel’s billable-weight estimate, use the chargeable-weight calculator. Your entries stay in this browser and are not uploaded by the calculator.
