Volume Weight Formula:
| From: | To: |
Volume 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 volume weight formula:
Where:
Explanation: The formula calculates the volumetric weight by dividing the cubic volume of the package by the standard dimensional factor of 166, which represents the space-to-weight ratio used in air freight pricing.
Details: Accurate volume weight calculation is crucial for determining shipping costs, optimizing packaging, and avoiding unexpected charges. Carriers charge based on whichever is greater - the actual weight or the volume weight.
Tips: Measure the outer dimensions of your package in inches. Enter length, width, and height. All values must be positive numbers. The result will be in pounds (lbs).
Q1: Why is volume weight important in air freight?
A: Air freight space is limited and expensive. Volume weight ensures that carriers are compensated fairly for bulky items that take up significant space but may be lightweight.
Q2: What is the 166 divisor based on?
A: The divisor 166 represents the standard dimensional factor in air freight, meaning 166 cubic inches equals 1 pound for pricing purposes.
Q3: How do carriers determine which weight to charge?
A: Carriers compare the actual weight and volume weight, then charge based on whichever is greater - this is called the chargeable weight.
Q4: Does this calculation apply to all air freight carriers?
A: Most major air freight carriers use this standard calculation, but some may use different divisors (like 139 for domestic shipments). Always check with your specific carrier.
Q5: How can I reduce volume weight charges?
A: Use more compact packaging, disassemble items when possible, or choose more efficient packaging materials to minimize the dimensional footprint of your shipment.
