What Is Volumetric Weight?
Volumetric weight estimates the space a package occupies and converts that volume into a weight value using a divisor. It is also commonly called dimensional weight or DIM weight.
Cargo calculator
Volumetric Weight Calculator
Calculate dimensional weight for multiple cartons or package types. Choose a preset or custom divisor, enter packed outer dimensions, and review the total volumetric weight with shipment CBM.

Understanding volumetric weight
Use these notes to verify dimensional-weight calculations and avoid common setup mistakes.
Volumetric Weight Formula
Length(cm) × Width(cm) × Height(cm) ÷ volumetric divisor
For multiple identical packages, multiply the volumetric weight per piece by the package quantity.
Why Does the Divisor Matter?
Different carriers, services, routes, and freight modes may apply different divisors. Verify the required divisor with your carrier or freight forwarder before using the result for shipping decisions.
Volumetric Weight Calculation Example
A carton measuring 50 cm × 40 cm × 30 cm has a volume of 60,000 cm³. With a 5000 divisor, 60,000 ÷ 5000 = 12 kg per carton. For 10 cartons, 12 × 10 = 120 kg volumetric weight.
5000 vs 6000 Divisor
For a 50 cm × 40 cm × 30 cm carton, a 5000 divisor gives 12.00 kg, while a 6000 divisor gives 10.00 kg. Mathematically, a smaller divisor produces a larger volumetric-weight result.
Volumetric Weight vs Actual Weight
Actual weight is measured on a scale. Volumetric weight is calculated from dimensions. Some shipping services compare the two, but the final chargeable-weight method depends on the carrier or service. A dedicated Chargeable Weight Calculator is planned.
Volumetric Weight vs CBM
CBM measures volume, while volumetric weight converts volume into a weight-equivalent value using a divisor. For pure shipment volume, use the CBM Calculator.
Common Volumetric Weight Mistakes
- Using product dimensions instead of packed carton dimensions.
- Using the wrong divisor for the carrier or service.
- Mixing units without converting them correctly.
- Forgetting to multiply by package quantity.
- Confusing volumetric weight with actual weight.
- Assuming every carrier uses the same calculation rule.
FAQ
Volumetric Weight Calculator FAQ
What is volumetric weight?+
Volumetric weight is a calculated weight based on the space a packed carton occupies, using its dimensions and a shipping divisor.
Is volumetric weight the same as dimensional weight?+
Yes. Volumetric weight, dimensional weight, and DIM weight usually refer to the same calculation concept.
How do I calculate volumetric weight?+
Convert dimensions to the units required by the divisor, multiply length by width by height, divide by the divisor, then multiply by quantity.
What divisor should I use?+
Use the divisor specified by your carrier, service, route, or freight forwarder. CargoMeasure includes common numeric presets but does not treat them as universal rules.
What is the difference between 5000 and 6000?+
For the same carton, a 5000 divisor produces a larger volumetric-weight result than a 6000 divisor.
Does actual weight affect volumetric weight?+
No. Volumetric weight is calculated from dimensions. Some services compare it with actual scale weight when deciding chargeable weight.
Can I calculate multiple cartons?+
Yes. Add up to 20 package types and enter a quantity for each type.
Should I use carton dimensions or product dimensions?+
Use packed outer carton dimensions, including packaging and protective material, unless your carrier instructs otherwise.
What is the difference between CBM and volumetric weight?+
CBM measures volume. Volumetric weight converts that volume into a weight-equivalent value using a divisor.
