What is CBM Calculator?

A CBM (cubic metre) calculator computes the volume of a shipment in cubic metres from its length, width, and height.

CBM is the standard unit for freight charges — shipping costs are often quoted per cubic metre.

How does the CBM Calculator work?

CBM = Length (m) × Width (m) × Height (m)

The calculator multiplies the three dimensions, converting from cm or inches if needed.

It also estimates the freight charge using a rate per CBM.

How to use the CBM Calculator?

  1. Enter the length, width, and height of the shipment.
  2. Select the unit (cm, m, inches).
  3. The calculator shows the volume in CBM and the estimated freight cost.
