Dimensional Weight Formula:
From: | To: |
Dimensional weight (also called volumetric weight) is a pricing technique used by airlines and freight carriers that considers both the actual weight and volume of a package. It represents the density of a package and is used to determine shipping costs.
The calculator uses the dimensional weight formula:
Where:
Explanation: The formula calculates the volumetric weight by multiplying the three dimensions and dividing by a standard dimensional factor (166 for inches/lbs).
Details: Airlines charge based on whichever is greater - the actual weight or the dimensional weight. This ensures fair pricing for lightweight but bulky items that occupy significant cargo space.
Tips: Enter package dimensions in inches. All values must be positive numbers. The result shows the dimensional weight in pounds that airlines will use for billing purposes.
Q1: Why do airlines use dimensional weight?
A: Airlines use dimensional weight to account for the space a package occupies in the aircraft, ensuring they charge appropriately for bulky but lightweight items.
Q2: What is the 166 divisor based on?
A: The 166 divisor represents the volumetric conversion factor for inches to pounds, based on industry standards for air cargo density calculations.
Q3: How do I measure package dimensions correctly?
A: Measure to the farthest points including any bulges or protrusions. Round up to the nearest whole inch for airline calculations.
Q4: What if my package is irregularly shaped?
A: For irregular shapes, use the smallest rectangular box that can contain the item to determine the dimensional weight.
Q5: Do all airlines use the same dimensional factor?
A: While 166 is standard for most airlines, some carriers may use different factors. Always check with your specific airline for their current rates and factors.
