Volume Weight Formula:
| From: | To: |
Volumetric weight (also known as dimensional weight) is a pricing technique used in air freight that considers both the weight and volume of a package. It reflects the density of the package, as lighter but larger items take up more space in aircraft.
The calculator uses the volumetric weight formula:
Where:
Explanation: The formula calculates how much space a package occupies relative to its actual weight, with 6000 cm³ per kg being the standard air freight conversion factor.
Details: Airlines charge based on whichever is greater - the actual weight or volumetric weight. This ensures fair pricing for lightweight but bulky items that consume valuable cargo space.
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 6000 used as the divisor?
A: 6000 cm³/kg is the standard volumetric conversion factor for air freight, representing the space-to-weight ratio that airlines use for pricing calculations.
Q2: How does volumetric weight differ from actual weight?
A: Actual weight is the physical mass measured on a scale, while volumetric weight calculates the "space" the package occupies and converts it to an equivalent weight.
Q3: Which weight is used for charging - actual or volumetric?
A: Airlines charge based on the chargeable weight, which is the greater of the actual weight or volumetric 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: How can I reduce volumetric weight charges?
A: Use more compact packaging, disassemble items if possible, or choose denser packaging materials to minimize the external dimensions of your shipment.
