CBM Calculator for Export and Import Shipping

Our free CBM Calculator is designed for exporters, importers, freight forwarders, shipping professionals and businesses that need to calculate cargo volume quickly. Enter carton length, width, height, weight and quantity to calculate CBM, cubic meter, cubic feet, total cargo weight and volumetric weight.

This CBM Calculator India can also be used by Indian exporters, importers, freight forwarders and logistics businesses planning international shipments. CBM is widely used to estimate the physical space occupied by cartons, boxes, pallets and other packed cargo.

What Does CBM Mean? CBM Full Form

CBM full form is Cubic Meter. CBM is a unit used to measure cargo volume. In international shipping, logistics, export and import, CBM helps estimate the space occupied by packed cargo.

CBM and m³ are the same volume unit. Therefore, 1 CBM = 1 m³. CBM measures volume, while kilograms (KG) measure weight.

What Is 1 CBM in Shipping?

1 CBM in shipping means one cubic meter of cargo volume. It represents the space occupied by cargo, not its weight. The weight associated with 1 CBM depends on the density of the cargo and the applicable freight rules.

How to Calculate CBM

To calculate CBM, multiply the length, width and height of the packed package after converting all measurements into meters. For multiple packages with the same dimensions, multiply the volume of one package by the quantity.

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

How to Calculate CBM From Centimeters

Multiply length, width and height in centimeters and divide by 1,000,000.

CBM = Length (cm) × Width (cm) × Height (cm) ÷ 1,000,000

CBM Calculation Example

For a carton measuring 50 cm × 40 cm × 30 cm:

50 × 40 × 30 = 60,000 cm³
60,000 ÷ 1,000,000 = 0.06 CBM

If you have 100 cartons of the same size, total shipment volume is 0.06 × 100 = 6 CBM.

How to Calculate CBM to KG

There is no universal fixed conversion from CBM to KG. CBM measures volume, whereas KG measures weight. To estimate the actual weight from a volume, you need the cargo density: Weight (kg) = Volume (m³) × Density (kg/m³). Freight carriers may also apply separate volumetric or weight/measurement rules.

Weight (kg) = CBM × Cargo Density (kg/m³)

CBM to CFT – Cubic Meter to Cubic Feet

One cubic meter is approximately equal to 35.3147 cubic feet (CFT). This conversion is useful when cargo measurements are supplied in different units.

1 CBM ≈ 35.3147 CFT

Shipping Volume Calculator

A Shipping Volume Calculator helps exporters and importers estimate the total space occupied by cartons, boxes or other packed cargo. Enter dimensions and quantity to calculate the shipment's total CBM before requesting freight rates or planning container space.

Sea Freight Volumetric Weight

Sea freight may use a volume-based weight or weight/measurement (W/M) calculation. For planning purposes, this calculator uses approximately 1,000 kg per CBM. Actual freight rating rules vary by carrier, route, commodity and shipment terms.

Air Freight Volumetric Weight

Air freight commonly uses dimensional or volumetric weight. A commonly used planning factor is approximately 167 kg per CBM, based on a 6000 cm³/kg divisor. Airlines and courier companies may use different rules, so confirm the applicable divisor with the carrier.

20 FT Container CBM Calculator

A standard 20 ft dry container has a theoretical internal volume of approximately 33 CBM. Practical usable space can be lower because of packaging, cargo shape, loading method and weight restrictions.

40 FT Container CBM Calculator

A standard 40 ft dry container has a theoretical internal volume of approximately 67–68 CBM. Actual loading capacity depends on cargo dimensions, weight and loading arrangement.

40 HC Container CBM Calculator

A 40 ft High Cube (40 HC) container has a theoretical internal volume of approximately 76 CBM. Actual usable space depends on cargo dimensions, packaging, loading method and weight limits.

CBM Calculator for LCL and FCL Shipping

CBM is important when planning LCL (Less than Container Load) and FCL (Full Container Load) shipments. Knowing total cargo volume helps when comparing shipping options, requesting freight quotations and preparing packing information.

Export Packing and Shipment Planning

Accurate carton dimensions, quantity and weight are important for international shipment planning. Exporters and importers can use CBM calculations to estimate cargo space and communicate shipment details to freight forwarders and shipping companies.
