How to convert from CBM to cuft?
Multiply the CBM value by 35.3146667, or divide by 0.0283168466, to get the equivalent cuft value.
What is CBM?
CBM (cubic meter) is a commonly used metric unit for measuring volume. A space in which all sides are one meter (or 100 centimeters) long would equal one CBM.
Cubic meter can also be denoted as M3. So 6.5 cubic meter can be written as either 6.5 CBM or 6.5 M3.
It is used in the cargo transportation / shipping industry to measure the volume of cargo shipments that are being moved, in order to calculate freight cost or estimate the required loading space.
What is cuft?
The imperial counter part of CBM is cuft, or cubic foot. A space in which all sides are one foot (12 inches, or 30.48 cm) long would equal to one cubic foot.
Cubic foot can also be expressed as ft3. So 31 cubic feet can be noted as either 31 cuft or 31 ft3.
Although metric units are being adopted by most parts of the world, the shipping and manufacturing industries are still using cuft for cargo and shipments heavily.
Reason is that most boxes of goods are comparatively much smaller than 1 CBM. Using it exclusively would cause calculation or paperwork inconveniences.
Then there are also the cubic centimeter and cubic inch. Due to both being relative small amount of spaces, they are impractical for the purpose of shipment volume calculations. That's why the cuft stayed widely used dispite not being a metric unit.
Note that centimeters and inches themselves are still important in volume calculations, since most boxes and crates that make up the shipments are still measured in these two units.
