CargoKit

Cubic Feet Calculator

Calculate cubic feet (ft³) from carton dimensions, with CBM alongside.

How it works

Enter dimensions in any unit. CargoKit converts to cubic meters internally, then outputs cubic feet, CBM, and liters.

Formula

ft³ = (Length × Width × Height × Quantity) × 35.315

Worked example

80 cm × 60 cm × 50 cm × 10 = 2.400 m³ × 35.315 = 84.755 ft³

Frequently asked questions

How do I convert CBM to cubic feet?

When are cubic feet used in freight?

Cubic feet are used primarily for US domestic freight, LTL (less-than-truckload) shipments, and some US-based parcel carriers.
