Enter the size of a box and how many you have. This gives the cubic feet of one box, the whole lot, and the same total in cubic metres.
Cubic feet is the space a box takes up. Carriers, warehouses and freight forwarders all use it.
One cubic foot is 1,728 cubic inches, a box 12 inches on every side. One cubic metre is about 35.31 cubic feet.
Measure the length, width and height of the box in inches. Multiply the three together. Divide the answer by 1,728. If you measured in feet, multiply the three and you are done. If you measured in centimetres, multiply them and divide by 28,317.
(Length × Width × Height in inches) ÷ 1,728 = cubic feet
A box 24 × 18 × 12 in is 5,184 cubic inches. Divided by 1,728, that is 3 cubic feet. Ten of them are 30 cubic feet, or 0.85 cubic metres.
Freight class. LTL density is weight divided by cubic feet, and density sets the class. The freight class calculator does the whole sum.
Dimensional weight. Parcel carriers divide cubic inches by a divisor and bill on the result when it beats the scale. The dimensional weight calculator handles the divisors.
Ocean freight. Container space is quoted in cubic metres, so the metric total is the one a forwarder asks for.
Storage. Many warehouses bill space by the cubic foot or by the pallet. At BoxHero storage sits inside a flat monthly retainer with no overage charge.
1,728. A cubic foot is 12 inches by 12 inches by 12 inches.
Multiply by 0.0283. One cubic metre is about 35.31 cubic feet.
Measure the outside of the packed box. That is the size carriers and warehouses measure.
Yes. For parcels, the cubic size of the box drives dimensional weight. For freight, cubic feet sets density and so the class. Either way a bigger box costs more.
