The Hesapstan volumetric weight calculator is designed to calculate a cargo package's volumetric weight (desi value) from its width, height and length measurements. Shipping carriers typically charge based on whichever is larger: the actual weight or the volumetric weight.
What is desi and how is it calculated?
Desi is volumetric weight calculated from package volume. The formula is (width × height × length) / selected divisor; the tool supports 3000, 4000, 5000 and 6000.
For example, for a 40 cm × 30 cm × 50 cm box, desi = (40 × 30 × 50) / 3000 = 20. If the package's actual weight is below 20 kg, shipping cost is typically based on the desi value instead.
The 3000 divisor used in this tool is a widely used industry convention for domestic/ground cargo, not an official government rate. Some carriers or air-freight services use a different divisor; check your carrier's current rate for exact pricing.
How does desi affect shipping cost?
Carriers typically compare a package's actual weight to its calculated desi value and charge based on whichever is larger. This means light but bulky packages (foam, boxes, furniture parts) can sometimes cost much more than their actual weight would suggest.
This tool only calculates the desi value — it does not calculate the shipping cost itself, since cost depends on each carrier's current rate card.
What does this tool not calculate?
- It does not calculate a carrier's actual shipping fee; that depends on the carrier, distance and promotions.
- It does not decide which divisor a carrier or service contract requires; select the confirmed divisor.
- It does not sum multiple packages; each package must be calculated separately.
Frequently Asked Questions
How is desi calculated?
Desi = (width × height × length) / 3000. Measurements are entered in centimeters.
Is the 3000 divisor always correct?
No. 3000 is a common industry convention for domestic/ground cargo; some carriers or air freight services use a different divisor. Check your carrier's current rate for exact pricing.
Is desi or actual weight used for pricing?
Carriers typically use whichever is larger. Bulky but light packages can have a higher desi value than actual weight.
Does this tool calculate the shipping cost too?
No. It only calculates the desi (volumetric weight) value. Cost depends on each carrier's own rate card.
