Purpose: This article explains volumetric weight and how to calculate it.
Volumetric weight vs actual weight
What is volumetric weight?
Volumetric weight is the ‘volume’ that a package occupies when in transit (the physical size of a package).
What is actual weight?
The actual (or physical) weight of a package is its actual weight measured in kilograms.
The amount of space a package occupies (volumetric weight) in transit is regarded as equally as important as how much it weighs (actual weight) by shipping companies.
How to calculate volumetric weight
The most common means to calculate volumetric weight is by multiplying the length, width, and height of a parcel (in cm) and dividing that figure by 5000 (some carriers use a divisor of 4000).
Often the price of your shipment is dictated by the volumetric weight of your parcel(s) rather than the actual weight.
Using a calculator:
- Multiply the parcel’s three dimensions (length x height x width)
- If you are using centimeters then divide the result by 5000
- If you are using inches then divide the result by 305
- The resulting figure represents the volumetric weight of your parcel
The courier will compare the volumetric weight to the actual weight of a parcel and charge whichever is the greater of the two (also known as billable weight or chargeable weight).
