Volumetric weight calculator
Enter carton dimensions and actual weight to calculate volumetric weight using your carrier’s divisor, then compare it with actual weight to determine chargeable weight. Add multiple packages and choose metric or imperial units and from common divisors.
Settings
Set unit system, volumetric factor, and rounding for every package.
Packages
Volumetric weight = L × W × H × qty ÷ factor. If actual weight is empty, chargeable equals volumetric; if filled, chargeable is the greater of that package’s actual total and volumetric weight.
Unit system, factor, and rounding apply to every package. Rename packages and set quantity as needed. With more than one package, the shipment total is the sum of each package’s chargeable weight — not all dimensions added first, then divided.
Choose the factor your carrier uses. Metric: 5000 (cm/kg) is common for international express, 6000 for air or postal, 8000 for some economy lanes. Imperial: 139, 166, and 194. You can enter a custom factor; it should match the current unit system, or the result may not match the invoice.
No rounding by default. Some carriers round volumetric and chargeable weight up: to 1 for whole kg or lb, to 0.5 for half kg or half lb.
