Dimensional Weight Calculator for Air Freight
Answer: Dimensional weight for air freight is carton volume converted to kilograms with a divisor, then compared with actual weight for chargeable-weight billing.
Dimensional weight for air freight is calculated as packed length x width x height converted to cubic centimeters, multiplied by carton quantity, then divided by the air freight divisor.
How the calculation works
This page is an exact-match variant for the search phrase “dimensional weight calculator for air freight.” The canonical general page for this formula is the Air Freight Dim Weight Calculator. If you need the final billed kilograms, use the Air Freight Chargeable Weight Calculator because air freight normally bills the higher of actual gross weight and dimensional weight.
dimensional weight kg = length cm x width cm x height cm x quantity / divisorUse 6000 cm3/kg for standard air freight planning unless the carrier or forwarder gives a different divisor. Use 5000 cm3/kg for many express courier and parcel-style air services. If you enter actual gross weight, the widget also shows a quick chargeable-weight check, but the canonical final-billing workflow remains the chargeable-weight calculator.
FAQ
Is this the canonical air freight dim weight calculator?
No. This is an exact-match page for the longer keyword “dimensional weight calculator for air freight.” The canonical formula page is /tools/air-freight-dim-weight-calculator/.
When should I use the chargeable-weight calculator?
Use /tools/air-freight-chargeable-weight-calculator/ when you need the final billing weight. Chargeable weight compares dimensional weight with actual gross weight and uses the higher value.
What divisor should I use for standard air freight?
Use 6000 cm3/kg for standard international air freight planning unless your quote, airline, or forwarder contract specifies another divisor.
When does the 5000 divisor apply?
The 5000 cm3/kg divisor is common for express courier, parcel-style air, and stricter ecommerce air services. It produces a higher dimensional weight than 6000 for the same cartons.
Is dimensional weight the same as volumetric weight?
In most air freight quoting, dimensional weight, dim weight, volumetric weight, and volume weight mean the same thing: shipment volume converted into kilograms.
Should I enter product size or carton size?
Enter the outside packed carton, crate, or pallet dimensions. Carriers bill the freight as tendered, not the loose product dimensions inside the packaging.
Can dimensional weight be lower than actual weight?
Yes. Dense cargo can have dimensional weight below actual gross weight. In that case, actual weight normally becomes the chargeable-weight basis.
Does this calculator include freight rates?
No. It calculates the weight basis only. Rate per kg, minimum charges, surcharges, pickup, delivery, customs, and current airline capacity require a quote or rate calculator.
