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 calculates the volumetric weight by dividing the package volume by the standard air freight divisor of 6000 cm³ per kilogram.
Details: Air freight charges are based on whichever is greater - the actual weight or the volumetric weight. Accurate calculation prevents unexpected costs and ensures proper pricing for shipping services.
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 volumetric weight used in air freight?
A: Air freight space is limited and expensive. Volumetric weight ensures carriers are compensated for the space occupied by lightweight but bulky items.
Q2: What is the 6000 divisor based on?
A: The 6000 cm³/kg divisor is the IATA standard, representing the space-to-weight ratio that determines when volume becomes the charging factor.
Q3: How do I measure package dimensions correctly?
A: Measure the outer dimensions at the longest points including any bulges or protrusions. Round up to the nearest centimeter.
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.
Q5: Do all air freight carriers use the same divisor?
A: While 6000 is standard for air freight, some carriers may use different divisors. Always check with your specific carrier for their requirements.
