Volume Weight Formula:
| From: | To: |
Volume weight (also known as dimensional weight) is a pricing technique used in air freight that considers both the actual weight and the volume of a package. It ensures that lightweight but bulky items are charged appropriately for the space they occupy.
The calculator uses the standard air freight volume weight formula:
Where:
Explanation: The formula calculates the volume weight in kilograms by dividing the cubic volume by 6000, which represents the density factor used in air freight calculations.
Details: Air carriers charge based on whichever is greater - the actual weight or the volume weight. This ensures fair pricing for both dense and lightweight cargo, optimizing aircraft space utilization and revenue management.
Tips: Enter the external dimensions of your package in centimeters. Measure the longest points for each dimension. All values must be positive numbers greater than zero.
Q1: Why is 6000 used as the divisor?
A: 6000 is the standard volumetric divisor for air freight, representing 6 cubic meters per metric ton (1,000,000 cm³ ÷ 166.67 kg = 6000 cm³/kg).
Q2: How does volume weight affect shipping costs?
A: Carriers charge based on the higher value between actual weight and volume weight. If volume weight exceeds actual weight, you pay based on volume weight.
Q3: Are there different divisors for different carriers?
A: While 6000 is standard for air freight, some carriers may use 5000 for more favorable pricing. Always check with your specific carrier.
Q4: How should I measure irregularly shaped packages?
A: Measure the longest points in each dimension to create the smallest rectangular box that can contain your item.
Q5: What's the difference between volume weight and chargeable weight?
A: Volume weight is the calculated dimensional weight, while chargeable weight is the greater of actual weight or volume weight used for billing.
