What is a CBM Calculator and How does it work?

A CBM calculator is an essential tool in logistics, used to measure the Cubic Meter (CBM) of cargo. It helps shippers and freight forwarders determine the total volume of shipments by taking into account the cargo's length, width, and height. CBM is critical for effective load planning, as it determines how much space the cargo will occupy in a shipping container, optimizing the packing process and ensuring cost efficiency.

The CBM calculator automatically calculates the volume by utilizing the dimensions of the cargo, providing accurate results for both individual and multiple items. This not only assists in estimating the shipping costs but also ensures better space utilization within containers, improving operational efficiency. Freightmango's CBM calculator enhances this process by offering a user-friendly interface, ensuring precise volume assessments for streamlined logistics operations.

Steps to Use CBM Calculator for Less Than Container Load (LCL)

  1. Open the LCL Calculator by navigating to the section for Less Than Container Load (LCL) on the website.
  2. Enter the number of units you wish to ship.
  3. Now enter the weight of a single unit in kilograms (kgs) or pounds (lbs), selecting the appropriate unit of measurement.
  4. Move to the Measurement (LxWxH per unit) section and enter the length (L), breadth (B), and height (H) of each unit in centimeters (cm) or inches (in), selecting the correct unit of measurement.
  5. Check the "Total Volume" field to see the calculated volume in cubic meters (CBM) and check the "Total Shipment Weight" field to see the calculated weight in kilograms (KG).
  6. Your result will appear at the bottom of the calculator.

Steps to Use CBM Calculator for Air Freight

  1. Open the Air Freight Calculator by navigating to the Air Freight section on the calculator.
  2. Enter the number of units you wish to ship in the "Unit" field.
  3. Now enter the weight of a single unit in kilograms (kgs) or pounds (lbs), selecting the appropriate unit of measurement.
  4. Move to the "Measurement (LxWxH per unit)" section and enter the length (L), breadth (B), and height (H) of each unit in centimeters (cm) or inches (in), selecting the correct unit of measurement.
  5. Check the "Total Volume" field to see the calculated volume in VWT and check the "Total Shipment Weight" field to see the calculated weight in kilograms (KG).
  6. Your result will appear at the bottom of the calculator, showing the estimated shipping cost.

Importance of using CBM Calculator?

Using a CBM (Cubic Meter) Calculator is crucial for optimizing the logistics and shipping process. It helps accurately determine the volume of goods to be transported, which is essential for several reasons:

Cost Estimation

Freight charges are often based on the cargo volume. Accurate CBM calculations ensure correct charges, avoiding overpayments or disputes with shipping companies.

Efficient Space Utilization

Knowing the exact volume allows for better planning of space in containers or trucks, reducing the number of shipments needed and cutting down costs.

Container Selection

Precise volume measurement helps select the right container size, ensuring neither underutilization nor overloading, which optimizes shipping efficiency.

Avoiding Surcharges

Incorrect volume calculations can lead to surcharges due to space wastage or the need for additional shipments. Using a CBM calculator helps avoid unexpected costs.

Regulatory Compliance

Accurate CBM calculations ensure compliance with shipping regulations, preventing delays and penalties associated with incorrect cargo volume declarations.

In summary, using a CBM calculator enhances efficiency, accuracy, and cost-effectiveness in the shipping process, making it an indispensable tool for logistics management.

Formula to Calculate CBM Manually?

cbm

CBM= [Length (cm)xWidth (cm)xHeight (cm)] / 1,000,000
If you have different-sized items, repeat the formula for each size and add up all the volumes to get the total CBM.

Example:

Suppose you have two types of items:

1. Item A= 5 items, each measuring 50 cm (L) x 40 cm (W) x 30 cm (H)

1. Item B= 3 items, each measuring 60 cm (L) x 50 cm (W) x 40 cm (H)

Calculate the CBM for each type:

  • CBM for Item A= 5x(50x40x30) / 1,000,000 = 5x0.06=0.3 CBM

  • CBM for Item B= 3x(60x50x40) / 1,000,000 = 3x0.12=0.36 CBM

Add the volumes to get the total CBM:

Total CBM= 0.3 +0.36= 0.66 CBM

Calculating CBM for Cylindrical Packages

cbm

CBM= πxr2xh
r = radius of the cylinder (in meters), h = height (or length) of the cylinder (in meters), π≈3.14159

Example:

Suppose you have two cylindrical packages:

Cylinder A: Diameter = 40 cm, Length = 100 cm

Cylinder B: Diameter = 50 cm, Length = 120 cm

First, convert the dimensions to meters (since CBM is in cubic meters):

Cylinder A:

Diameter = 40 cm → Radius = 20 cm = 0.2 m

Length = 100 cm = 1 m

Cylinder B:

Diameter = 50 cm → Radius = 25 cm = 0.25 m

Length = 120 cm = 1.2 m

Calculate the CBM for each cylinder:

CBM for Cylinder A:

CBM=π×(0.2)2×1=3.14159×0.04×1=0.1257 CBM

CBM for Cylinder B:

CBM=π×(0.25)2×1.2=3.14159×0.0625×1.2=0.2356 CBMCBM=π×(0.25)2×1.2=3.14159×0.0625×1.2=0.2356 CBM

Total CBM

Add the volumes of the different sizes to get the total CBM:

Total CBM= 0.1257+0.2356= 0.3613
