Use the formula: CBM = L × W × H
Where L = Length of Cube/package/carton
W = Width of Cube/package/carton
H = Height of Cube/package/carton
(Cubes are most used in shipments so first we had taken the Cube for CBM Calculation)
Cubic meters (CBM or m³) are a measure of volume used in the metric system to quantify the amount of space occupied by an object or substance. Calculating CBM can be straightforward if you have the necessary measurements. The formula for calculating CBM depends on the shape of the object you are measuring. Here are some common shapes and their corresponding CBM formulas:
Cuboid or Rectangular Prism:
Use the formula: CBM = L × W × H Measure the length (L), width (W), and height (H) of the object in meters.
Measure the radius (r) of the circular base and the height (h) of the cylinder in meters.
Use the formula: CBM = π × r² × h
Measure the radius (r) of the sphere in meters.
Use the formula: CBM = (4/3) × π × r³
Measure the radius (r) of the circular base and the height (h) of the cone in meters.
Use the formula: CBM = (1/3) × π × r² × h
Measure the base area (A) and the height (h) of the pyramid in meters.
Use the formula: CBM = (1/3) × A × h
If you have an irregularly shaped object, you can estimate its CBM by dividing it into smaller, more regular shapes (like cubes or rectangles), calculating the CBM of each, and then summing them up.
Remember to use consistent units (usually meters) for all measurements to get the volume in cubic meters (CBM). If your measurements are in different units, you’ll need to convert them to meters before using the formulas.
Also, keep in mind that if you have an object made up of multiple parts, you should calculate the CBM for each part separately and then add them together to get the total CBM for the entire object.
