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 volumetric weight formula:
Where:
Explanation: The formula converts the volume of the package into an equivalent weight based on the density that carriers use to determine chargeable weight.
Details: Accurate volumetric weight calculation is crucial for air freight pricing. 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, widest, and highest points. All values must be positive numbers greater than zero.
Q1: Why is the divisor 6000 for air shipments?
A: The divisor 6000 (cm³/kg) is the standard conversion factor used by most air freight carriers to calculate volumetric weight based on the density they consider optimal for aircraft space utilization.
Q2: How is chargeable weight determined?
A: Chargeable weight is the greater of the actual weight and the volumetric weight. Carriers use this to ensure they're compensated appropriately for the space occupied.
Q3: Does this apply to all air shipments?
A: Most international air freight carriers use volumetric weight calculations, though some may use different divisors (5000 or 6000 are most common).
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. Measure the longest points in each dimension.
Q5: Are there different divisors for different modes of transport?
A: Yes, sea freight typically uses 1000, while road freight may use 3000 or 5000 depending on the carrier and region.
