Measure the packed cartons before comparing freight
CBM means cubic metres: it describes volume. It is useful for a multi-carton consignment, but it is not a price, a universal billing rule or confirmation that the goods can travel.
Ask about the packed shipmentKeep volume and weight as separate measurements
Measure the final external dimensions of each packed carton and record its gross weight. Keep a carton list when boxes differ; one average box can hide an important difference.
Some services use volume for consignment pricing, while others use actual or volumetric weight. The selected service determines its billing and rounding rules.
Make a carton list that can be checked
Final external dimensions
Length, width and height after packing, with the unit shown for every carton.
Carton count
State how many cartons share the same measurements; list different cartons separately.
Gross weight
Record the packed weight of each carton as well as the total where available.
Contents and delivery
Exact goods, restricted attributes, destination address and any special receiving requirements.
The example only teaches volume measurement. It is not a JTLGO freight quote, minimum charge, cargo acceptance or universal volumetric-weight factor.
Illustrative example: four identical packed cartons
- Length
- 60 cm
- Width
- 40 cm
- Height
- 40 cm
- Cartons
- 4
Volume per carton
60 × 40 × 40 ÷ 1,000,000 = 0.096 m³
Total volume
4 × 0.096 = 0.384 m³
Convert centimetres into cubic metres
For dimensions in centimetres, multiply length × width × height and divide by 1,000,000 to obtain cubic metres. For the example, 60 × 40 × 40 cm equals 0.096 m³ per carton.
Multiply by four only because all four cartons have the same final measurements. For different cartons, calculate each volume and add the results: do not silently substitute an average.
A calculated volume is not the final freight charge
The actual service may have a minimum billable volume, rounding, weight limits, packing conditions and separately reviewed charges. Those conditions must come from the specific offer.
A shipment can also require manual cargo review. An available CBM calculation does not establish an available shipping service, a battery service or a duty-paid parcel option.
Questions before shipping
What does CBM mean in shipping?
CBM means cubic metres and measures volume. A packed carton’s length, width and height determine its volume. CBM does not, by itself, state the freight charge, billable weight or whether JTLGO can accept its contents.
Can I multiply one carton’s volume by the number of cartons?
Yes, if every packed carton has the same dimensions. If sizes differ, calculate and add each carton’s volume. Keep the corresponding gross weights and contents so JTLGO can review the real consignment.
Is 0.384 m³ the price or minimum for this shipment?
No. The 0.384 m³ figure is only the calculated volume of four identical 60 × 40 × 40 cm cartons. The example does not specify a freight price, minimum charge or available shipping service.
Does a CBM estimate include duties, packing and delivery?
Not automatically. The written service offer must state the measurement basis, included work, tax responsibility, delivery scope and any separately reviewed charges. A volume calculation alone cannot provide those answers.
