Formula
Volumetric weight formula
Multiply length, width, and height, then divide by the carrier's volumetric divisor.
How to use this calculator
- Enter packed parcel inputs
Choose one unit system and enter the packed length, width, height, carrier divisor, and actual weight.
- Compare both weights
Review dimensional weight beside actual weight to identify the likely chargeable weight.
- Check carrier rules
Use the result for planning, then confirm the service divisor and rounding rules with your carrier.
Worked example
Example inputs
- Packed dimensions
- 40 × 30 × 20 cm
- Carrier divisor
- 5000
- Actual weight
- 3 kg
Calculation
40 × 30 × 20 ÷ 5000 = 4.8 kg; max(4.8 kg, 3 kg) = 4.8 kg.
What the result means
4.8 kg chargeable weight before service-specific rounding.
How to use the result
Carriers generally charge the greater of dimensional and actual weight, subject to the selected service's rounding rules.
Common mistakes
- Mixing centimetres with a divisor intended for inches.
- Using product-only dimensions instead of the packed parcel.
