IATA Volumetric Weight Formula:
| From: | To: |
Volumetric weight (also known as dimensional weight) is a pricing technique used by air freight carriers to account for the space a package occupies in relation to its actual weight. It ensures that lightweight but bulky items are charged appropriately for the space they consume.
The calculator uses the IATA volumetric weight formula:
Where:
Explanation: The formula converts the volume of a package into an equivalent weight value, allowing carriers to charge based on whichever is greater - actual weight or volumetric weight.
Details: Accurate volumetric weight calculation is crucial for air freight pricing, cargo space optimization, and ensuring fair charges for both shippers and carriers. It prevents revenue loss for carriers shipping 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 for accurate calculation.
Q1: Why is 6000 used as the divisor?
A: 6000 is the standard IATA volumetric divisor for air freight, representing the conversion factor between volume and weight for air cargo calculations.
Q2: How is volumetric weight used in shipping charges?
A: Carriers compare the volumetric weight with the actual weight and charge based on whichever is higher - this is called the chargeable weight.
Q3: Does this formula apply to all air freight?
A: While 6000 is the IATA standard, some carriers or regions may use slightly different divisors. Always check with your specific carrier.
Q4: What if my package is irregularly shaped?
A: For irregular shapes, use the dimensions of the smallest rectangular box that can contain the item (the bounding box dimensions).
Q5: How can I reduce volumetric weight charges?
A: Use efficient packaging, compress items when possible, and choose packaging that minimizes empty space while still providing adequate protection.
