Volumetric Weight Calculator

The cost of shipping a parcel sometimes reflect the space taken up on an aircraft, rather than the parcel’s actual weight. This is called the “volumetric” or “dimensional” weight. Use the calculator below to help determine whether you’ll be charged based on the physical or volumetric weight of your parcel.

Chargeable Weight Calculator: FAQs

What is volumetric weight?

Volumetric weight – also called dimensional weight – is used by carriers to account for low-density parcels that weigh little but take up significant space. The higher of the physical and volumetric weight is used to calculate shipping cost.

How is volumetric weight calculated?

The volumetric weight formula is:

(Length * Width * Height) / Shipping Factor

The most common shipping factors (used in Worldnet International’s volumetric weight calculator are 5,000 for metric units and 139 for imperial units.

How do you calculate chargeable weight?

We built the volumetric weight calculator above to do the math for you! Simply choose your measurement units (kg/cm or lb/in) and the number of parcels you’ll be shipping, then enter the weight and dimensions of each parcel. The calculator will instantly tell you whether you’ll (likely) be charged on the physical or volumetric weight of your parcels.

Why is volumetric weight rounded?

Shipping carriers, like UPS, FedEx and DHL, round volumetric weight to the next pound or kilogram up. Our calculator accounts for this. Any non-zero weight less than 1 pound or kilogram will return a volumetric weight of “1.”
