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 volume weight formula:
Where:
Explanation: The divisor 166 represents the standard dimensional factor used in air freight calculations to convert cubic inches to pounds for pricing purposes.
Details: Accurate volume weight calculation is crucial for air freight shipping as carriers charge based on whichever is greater - the actual weight or the volume weight. This ensures fair pricing for both lightweight bulky items and dense heavy items.
Tips: Enter the package dimensions in inches (length, width, height). All values must be positive numbers. Measure the outer dimensions of your package at its longest, widest, and highest points.
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 the space occupied by lightweight but bulky packages.
Q2: What is the 166 divisor based on?
A: The divisor 166 is the standard dimensional factor for air freight, representing the volume (in cubic inches) that equals one pound for pricing purposes.
Q3: How do I measure package dimensions correctly?
A: Measure the outer dimensions at the longest, widest, and highest points. Round up to the nearest inch for irregular shapes.
Q4: What if my package has an irregular shape?
A: For irregular shapes, use the smallest rectangular box that can contain the item and measure that box's dimensions.
Q5: Do all carriers use the same dimensional factor?
A: While 166 is standard for air freight, some carriers may use different factors. Always check with your specific carrier for their current rates and factors.
