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 standard volumetric weight formula:
Where:
Explanation: The divisor 6000 represents the conversion factor from cubic centimeters to kilograms for air freight, based on the density ratio used in the air cargo industry.
Details: Air carriers charge based on whichever is greater - the actual weight or volumetric weight. This ensures fair pricing for both dense and lightweight cargo, optimizing aircraft space utilization and revenue management.
Tips: Enter the external dimensions of your shipment in centimeters. Measure at the longest points of each side. All values must be positive numbers greater than zero.
Q1: Why is volumetric weight important in air freight?
A: Aircraft have limited cargo space. Volumetric weight ensures that carriers are compensated fairly for bulky, lightweight items that take up valuable space.
Q2: What is the 6000 divisor based on?
A: The 6000 divisor assumes a standard density ratio of 1:6 (1kg per 6000 cubic cm), which is the industry standard for air cargo weight-to-space ratio.
Q3: How do I measure package dimensions correctly?
A: Measure the external dimensions at the longest points. Include any packaging, protrusions, or irregular shapes in your measurements.
Q4: Is the volumetric divisor the same for all carriers?
A: While 6000 is the IATA standard, some carriers may use different divisors (5000 or 4000). Always check with your specific carrier for their requirements.
Q5: What if my shipment has multiple packages?
A: Calculate the volumetric weight for each package separately, then sum all volumetric weights to get the total volumetric weight for the shipment.
