Dimensional Weight Formula:
| From: | To: |
Dimensional weight (also called volumetric weight) is a pricing technique for commercial freight transport that uses the volume of a package rather than its actual weight to calculate shipping costs. It reflects the density of a package.
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 volumetric divisor (5000 for air cargo).
Details: Airlines charge based on whichever is greater - the actual weight or dimensional weight. This ensures they are compensated for the space a package occupies, not just its mass.
Tips: Enter length, width, and height in centimeters. All values must be positive numbers. The result is in kilograms.
Q1: Why is dimensional weight important in air freight?
A: Air cargo space is limited and expensive. Dimensional weight ensures airlines charge appropriately for bulky, lightweight items that take up valuable cargo space.
Q2: What is the 5000 divisor based on?
A: The 5000 divisor represents a standard density ratio (6,000 cm³ per kg) commonly used in air freight calculations worldwide.
Q3: How do I measure package dimensions accurately?
A: Measure to the farthest points including any bulges or protrusions. Round up to the nearest centimeter for each dimension.
Q4: Do all airlines use the same divisor?
A: While 5000 is standard for air freight, some carriers may use different divisors (4000, 5000, or 6000). Always check with your specific carrier.
Q5: What's the difference between actual weight and dimensional weight?
A: Actual weight is the physical weight on a scale. Dimensional weight is calculated from package dimensions and represents the "space" the package occupies.
