What CBM means
CBM is cubic metres: the volume a shipment occupies. Ocean and air freight are quoted on it, and forwarders use it to work out whether you pay on volume or on weight, whichever is greater.
How it is calculated
Multiply length by width by height in metres. If you are working in centimetres, multiply the three figures and divide by 1,000,000. Multiply by the number of cartons for the shipment total.
CBM and freight class are not the same thing
CBM is a volume figure used mainly in international freight. LTL freight class in North America is based on density, which is weight divided by volume. If you are shipping domestically inside the United States you want the freight class calculator instead.
