VOLUME MEASUREMENT
THE BASICS

WHAT DOES CBM MEAN?

CBM stands for cubic meter. It is a measurement of how much three-dimensional space your cargo occupies.

Freight forwarders commonly use CBM when quoting LCL ocean freight, warehouse storage and cargo consolidation services.

A shipment that weighs relatively little can still take up a large amount of space, which is why both weight and volume are important in freight pricing.

1 CBM = 1 METER × 1 METER × 1 METER CBM measures volume, not weight. A lightweight carton and a heavy carton can occupy the same cubic volume.
CBM CALCULATION

HOW DO YOU CALCULATE CBM?

CBM FORMULA LENGTH × WIDTH × HEIGHT

Measurements must be in meters.

EXAMPLE

ONE CARTON

LENGTH 0.60 m
×
WIDTH 0.50 m
×
HEIGHT 0.40 m
= 0.12 CBM
DIMENSIONS IN CENTIMETERS?

CONVERT CM TO CBM.

Suppliers often provide carton dimensions in centimeters rather than meters.

You can calculate CBM directly from centimeters by dividing the result by 1,000,000.

USING CENTIMETERS L × W × H ÷ 1,000,000 Dimensions entered in centimeters
MULTIPLE CARTONS

HOW DO YOU CALCULATE TOTAL SHIPMENT CBM?

If all cartons have the same dimensions, calculate one carton first and multiply by the total carton quantity.

DIFFERENT CARTON SIZES?

CALCULATE EACH CARTON GROUP.

If your shipment contains cartons with different dimensions, calculate the CBM of each carton group separately and then add the results together.

01 CARTON TYPE A

Calculate dimensions × quantity.

02 CARTON TYPE B

Calculate dimensions × quantity.

03 CARTON TYPE C

Calculate dimensions × quantity.

04 ADD ALL CBM

The result is your total shipment volume.

WHY CBM MATTERS

WHERE IS CBM USED IN SHIPPING?

01

LCL SEA FREIGHT

LCL cargo shares container space with other shipments, so the amount of space your cargo occupies is an important part of pricing.

02

WAREHOUSE STORAGE

Cargo volume can affect how much warehouse space is required for temporary storage and consolidation.

03

FCL PLANNING

Total cargo volume helps determine whether your shipment may fit into a 20GP, 40GP or 40HQ container.

04

FREIGHT QUOTES

Providing accurate CBM allows a freight forwarder to compare transport methods and prepare a more accurate quotation.

VOLUME VS WEIGHT

CBM IS NOT THE SAME AS WEIGHT.

Weight tells us how heavy cargo is. CBM tells us how much physical space it occupies.

LCL SHARED CONTAINER
CBM & LCL SHIPPING

WHY IS CBM IMPORTANT FOR LCL?

With LCL shipping, several customers share the same container.

Because space is shared, freight quotations commonly consider the volume and weight of each individual shipment, together with origin and destination handling charges.

This is why accurate carton dimensions are particularly important when requesting an LCL quote.

CONTAINER PLANNING

DOES CBM TELL YOU WHICH CONTAINER TO USE?

CBM helps estimate space requirements, but container selection should not be based on CBM alone.

20GP 20-FOOT CONTAINER

Often considered for smaller full-container shipments or dense cargo.

40GP 40-FOOT CONTAINER

Offers greater internal volume for larger shipments.

IMPORTANT: Cargo shape, palletization, carton dimensions, maximum payload and loading method also affect how much cargo actually fits inside a container.
COMMON MISTAKES

CHECK THESE BEFORE SENDING A QUOTE REQUEST.

01 MIXING CM AND METERS

Make sure the formula matches the measurement unit used.

02 FORGETTING QUANTITY

One-carton CBM must be multiplied by the number of identical cartons.

03 USING PRODUCT SIZE

Freight calculations normally require packed carton dimensions rather than the bare product dimensions.

04 IGNORING PALLETS

Palletized cargo may occupy more volume than loose cartons.
