Cubic feet calculator
Measure it once. See it in cubic feet and cubic metres. Add the outside dimensions of boxes or rectangular items to build a volume list for your move.
How to calculate cubic feet from dimensions
For a rectangular object, multiply length by width by height using the same unit for all three measurements. Dimensions entered in feet give cubic feet directly. If you measure in inches, multiply the three dimensions and divide by 1,728. This calculator converts each dimension to metres first, then displays the result in both cubic metres and cubic feet.
Measure the outside of a packed box, including any bulges, rather than relying on a product description of its internal capacity. Enter a separate row for each different size. Quantity multiplies that row’s volume, so you do not need to repeat the dimensions for several identical cartons.
Cubic feet to cubic metres: a worked example
A box measuring 60 × 40 × 40 cm has a volume of 0.096 m³, or approximately 3.390 ft³. Five identical boxes total 0.480 m³, approximately 16.951 ft³. The initial row above uses one of these boxes as an example; replace its dimensions with your own measurements.
One cubic foot equals 0.028316846592 cubic metres. The calculator keeps the underlying values for its sums and rounds the displayed totals to three decimal places. Changing the measurement unit converts the dimensions already entered instead of interpreting the same numbers as a different physical size.
Measure furniture differently from loose belongings
For a simple furniture envelope, measure the widest, deepest and highest external points. Protruding arms, handles and packaging can matter. If an item will be dismantled, measure the packed components you actually plan to transport. Do not count both the assembled item and its components in the same inventory.
An envelope measurement includes empty space around an irregular object. It is useful for making a dimensions list, but cannot decide how that item will stack or whether another item can safely sit above it. For an awkward or delicate item, provide the mover with its measurements and handling requirements separately.
Why item volume is not a van or storage guarantee
The sum is geometric volume, not a loading plan. Real arrangements depend on item shapes, stackability, protection, access space and vehicle weight limits. A matching advertised van volume does not establish that your load fits safely. This tool does not calculate payload, number of trips or a removal quote.
Cubic volume is also different from storage floor area. Dividing volume by an assumed stack height can hide practical constraints. Use Stackt’s separate storage calculator for an item-based space enquiry, and confirm the eventual arrangement with the provider before booking. Keep your dimensions export as supporting information rather than a promised unit size.
Frequently asked questions
Can I measure in centimetres or inches?
Yes. Choose centimetres, metres, inches or feet. Every row uses the selected unit, and switching units converts valid dimensions already entered.
Does the calculator include packing space?
No automatic packing allowance is added. Enter packed outside dimensions. Gaps, access space and stacking restrictions still need a separate assessment.
Can I calculate several different box sizes?
Yes. Add a row for each size and enter the quantity for that row. Up to 50 rows are supported. Invalid or missing dimensions must be corrected before a complete total can be shown.
