What is volumetric weight?
Volumetric or dimensional weight converts the space a parcel occupies into a billing weight. Carriers can compare this result with actual weight when calculating charges.
Common formula
For dimensions in centimeters, a common form is Length × Width × Height ÷ Divisor. Divisors such as 5000 or 6000 are frequently seen, but the correct divisor depends on the carrier and service.
Example
A 50 × 40 × 30 cm parcel has 60,000 cm³ of volume. Using 5000 gives 12 kg of volumetric weight; using 6000 gives 10 kg.
Use the Volumetric Weight Calculator and confirm the divisor in your carrier quotation.
Quick answer
Estimate dimensional weight for air freight, courier and parcels. Use the values and units shown by the tool, review the result, and keep the original inputs available if you need to compare another scenario.
Practical checklist
- Confirm the units, dates, rates or source values before calculating.
- Use consistent units and avoid rounding intermediate values too early.
- Run a second scenario when you need to understand how one input changes the result.
- For regulated fees, taxes, provider rules or professional decisions, verify the current official rule before relying on the result.

Frequently asked questions
Should I use 5000 or 6000?
Use the divisor specified by your carrier or freight contract.
Why do different couriers give different volumetric weights?
Carriers can use different dimensional divisors, unit conventions and rounding policies.
Is volumetric weight the same as actual weight?
No. Actual weight is measured on a scale, while volumetric weight is calculated from package dimensions.
