Air Shipment Formula:
| From: | To: |
Dimensional weight (also known as volumetric 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 dimensional weight formula:
Where:
Explanation: The formula calculates how much space your package occupies and converts it to an equivalent weight for pricing purposes.
Details: Air carriers charge based on whichever is greater - the actual weight or the dimensional weight. Accurate calculation helps in cost estimation and prevents unexpected shipping charges.
Tips: Enter package dimensions in centimeters. Measure the outer dimensions at the longest points. All values must be positive numbers greater than zero.
Q1: Why is dimensional weight important in air freight?
A: Air cargo space is limited and expensive. Dimensional weight ensures that carriers are compensated for the space occupied by lightweight but bulky items.
Q2: What is the 6000 divisor based on?
A: The 6000 cm³/kg divisor represents the density ratio where 1 kg of cargo occupies 6000 cm³ of space in air freight calculations.
Q3: How do I measure package dimensions correctly?
A: Measure the longest points of each side - length, width, and height. Round up to the nearest centimeter for accuracy.
Q4: Do all air carriers use the same divisor?
A: While 6000 is standard for most international air freight, some carriers may use different divisors (5000 or 4000 for domestic services).
Q5: What if my package has an irregular shape?
A: For irregular shapes, use the dimensions of the smallest rectangular box that can contain your item.
