Volume Weight Formula:
| From: | To: |
Volume Weight (also known as dimensional weight) is a pricing technique used in air freight that considers package density. Airlines charge based on whichever is greater: actual weight or volume weight, to account for lightweight but bulky shipments.
The calculator uses the standard air freight volume weight formula:
Where:
Explanation: The formula calculates the volumetric weight by dividing the cubic volume by 5000, which represents the density ratio used in air cargo pricing.
Details: Accurate volume weight calculation is crucial for air freight cost estimation, shipment planning, and avoiding unexpected charges. Airlines use this to ensure they're compensated for the space occupied by lightweight cargo.
Tips: Enter package dimensions in centimeters. Measure the outer dimensions including packaging. All values must be positive numbers. The result is in kilograms.
Q1: Why is volume weight important in air freight?
A: Airlines charge based on the space cargo occupies. Volume weight ensures fair pricing for lightweight but bulky items that take up valuable cargo space.
Q2: What is the 5000 divisor based on?
A: The 5000 divisor represents a density ratio of 200 kg per cubic meter, which is the standard conversion factor used in air freight industry.
Q3: How do I measure package dimensions correctly?
A: Measure the longest points in each dimension including any protrusions and packaging materials. Round up to the nearest centimeter.
Q4: What if my shipment has multiple packages?
A: Calculate volume weight for each package separately, then sum all volume weights to get the total volumetric weight for the shipment.
Q5: Do all airlines use the same volumetric divisor?
A: While 5000 is standard, some carriers may use 6000 for specific services or regions. Always check with your airline or freight forwarder.
