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 standard air freight volumetric weight formula:
Where:
Explanation: The formula converts the volume of a package into an equivalent weight based on the density that air freight carriers use for pricing purposes.
Details: Accurate volumetric weight calculation is crucial for air freight shipping as carriers charge based on whichever is greater - the actual weight or the volumetric weight. This ensures fair pricing for both lightweight bulky items and dense heavy items.
Tips: Enter the package dimensions in centimeters. Measure the outer dimensions at the longest points. All values must be positive numbers greater than zero.
Q1: Why is 6000 used as the divisor?
A: 6000 is the standard volumetric divisor for air freight, representing 6000 cubic centimeters per kilogram, which is the density standard used by most airlines.
Q2: 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).
Q3: How do carriers determine which weight to charge?
A: Carriers compare the actual weight and volumetric weight, then charge based on whichever is greater (the chargeable weight).
Q4: Does this formula apply to all air freight?
A: While 6000 is standard for most air freight, some carriers or specific routes may use different divisors. Always check with your carrier.
Q5: What's the difference between air and sea freight volumetric weight?
A: Sea freight typically uses a divisor of 1000 (1 cubic meter = 1000 kg) instead of 6000, as sea transport can accommodate lower density cargo more efficiently.
