IATA Dimensional Weight Formula:
| From: | To: |
Dimensional weight (also called volumetric weight) is a pricing technique used by freight carriers that considers package density. The IATA (International Air Transport Association) uses the dimensional weight formula to calculate shipping costs based on the space a package occupies rather than its actual weight.
The calculator uses the IATA dimensional weight formula:
Where:
Explanation: The formula calculates how much space your package occupies in relation to its weight, helping carriers determine the most accurate shipping cost.
Details: Accurate dimensional weight calculation is crucial for international air freight as carriers charge based on whichever is greater - the actual weight or dimensional weight. This ensures fair pricing for lightweight but bulky items.
Tips: Enter package dimensions in centimeters. Measure the outer dimensions at the longest points. All values must be positive numbers greater than zero.
Q1: Why is dimensional weight important in air freight?
A: Air cargo space is limited and expensive. Dimensional weight pricing ensures carriers are compensated fairly for the space occupied by lightweight but bulky packages.
Q2: What is the 6000 divisor?
A: The 6000 divisor is the IATA standard volumetric conversion factor for air freight, representing the density ratio between weight and volume.
Q3: How do carriers determine which weight to use?
A: Carriers compare the actual weight and dimensional weight, then charge based on whichever is greater - this is called the chargeable weight.
Q4: Are there different divisors for different carriers?
A: While 6000 is standard for IATA air freight, some carriers or regions may use different divisors (5000 for some express carriers). Always check with your specific carrier.
Q5: How can I reduce dimensional weight costs?
A: Use appropriately sized packaging, compress items when possible, and consider disassembling bulky items to reduce the overall package dimensions.
