UPS Volumetric Weight Calculator
Estimate the volumetric (dimensional) weight UPS bills, using a divisor of 5000. Enter your parcel size to see the billable weight.
UPS's dimensional divisor
UPS uses a 5000 divisor on international air services and 139 in³/lb for US domestic. Large light parcels are billed on this dimensional weight.
The maths is the same for every carrier — only the divisor changes: (L × W × H in cm) ÷ 5000 gives the volumetric weight in kilograms. Compare it with your actual weight and UPS charges on whichever is greater.

Frequently asked questions
What divisor does UPS use for volumetric weight?
UPS uses a 5000 divisor in this calculation — one kilogram of volumetric weight per 5,000 cm³. Confirm it against the rate card for your specific service, as domestic and economy products can differ.
How is UPS chargeable weight decided?
UPS bills on the greater of actual and volumetric weight. If your box is large but light, the volumetric figure usually governs; if it is small and dense, the actual weight does.
Does packaging count toward volumetric weight?
Yes — carriers measure the outermost dimensions of the packed parcel, so the box, void fill and any overhang all add to the volumetric weight.
