Gross Weight to Chargeable Weight Calculator
Compare gross weight with volumetric weight using either total CBM
or package dimensions, then estimate the shipment’s chargeable weight.
JavaScript must be enabled to use this calculator.
Choose the freight rule and volume input
Gross weight must be compared with a volume-based equivalent.
Air freight volumetric weight is calculated from volume
using the selected divisor.
Switch methods without affecting the gross-weight unit.
Enter cubic centimetres per kilogram.
Chargeable weight = higher of gross weight or CBM × 166.67 kg
Advanced calculation options
Used only when package dimensions are selected.
Enter shipment details
Gross weight includes the goods and all packaging.
Include cartons, pallets, crates, wrapping, and protection.
Enter the combined cubic metres for the shipment.
Package dimensions
Add a separate line when package dimensions differ.
Add an optional freight-rate estimate
This estimate excludes minimum charges, zones, fuel, handling,
documentation, customs, delivery, storage, duties, taxes,
and surcharges.

Gross weight alone cannot determine chargeable weight; shipment volume
is also required. Confirm the applicable divisor, rounding,
measurements, minimums, and final charges with the carrier or
freight forwarder.
How Gross Weight Becomes Chargeable Weight
Gross weight is the physical weight of the goods plus every part of
the shipping package. Chargeable weight compares that gross weight
with a volume-based equivalent and uses the greater applicable result.
Air Freight
General air freight commonly divides package volume in cubic
centimetres by 6,000. This is equivalent to approximately
166.67 kilograms per CBM.
Express and Courier
Many express services use a 5,000 cm³/kg divisor, equivalent to
200 kilograms per CBM. Carrier and contract rules can differ.
Sea Freight LCL
LCL sea freight commonly compares shipment CBM with gross metric
tonnes, using one CBM as equivalent to 1,000 kilograms. FCL is
generally priced per container instead.
Using CBM or Dimensions
Select total CBM when the shipment volume is already known. Select
package dimensions when the calculator should derive CBM from
length, width, height, and quantity.
Why the Final Invoice May Differ
Carriers may reweigh or remeasure cargo and may apply different
divisors, minimums, rounding increments, package-level comparisons,
and surcharges.
Frequently Asked Questions
Can chargeable weight be calculated from gross weight alone?
No. Volume or package dimensions are needed to calculate and
compare volumetric weight.
What should gross weight include?
Include the goods, cartons, pallets, crates, wrapping,
cushioning, straps, and protective materials.
Which value becomes chargeable?
The greater applicable value between gross weight and
volumetric weight normally controls the estimate.
