About the CBM Calculator

What is a CBM Calculator?

A CBM Calculator (Cubic Meter Calculator) tells you the total shipping volume of your cargo so you can quote freight, choose the right container and avoid surprise volumetric weight charges. The free CBM Calculator on cbmchecker.com lets you enter the length, width, height, quantity and weight of every carton — in cm, m, in or ft — and instantly see the result in m³ and ft³, plus how much of a 20ft, 40ft, 40ft High Cube or 45ft High Cube container you've filled.

CBM formula

CBM = (Length × Width × Height) × Quantity — with all dimensions in meters. Our CBM Calculator handles the unit conversion automatically, so you can mix cm and inches without doing the math by hand.
