1. What is Chargeable Weight?

Chargeable Weight is the weight used by airlines to calculate shipping costs for air freight. It is determined by taking the greater value between the actual weight and the dimensional weight of a shipment.

2. How Does the Calculator Work?

The calculator uses the chargeable weight formula:

\[ \text{Chargeable Weight} = \max(\text{Actual Weight}, \frac{L \times W \times H}{166}) \]

Where:

\( \text{Actual Weight} \) — Physical weight of the shipment in pounds (lb)
\( L \) — Length of the shipment in inches (in)
\( W \) — Width of the shipment in inches (in)
\( H \) — Height of the shipment in inches (in)
\( 166 \) — Dimensional factor for air freight (cubic inches per pound)

Explanation: Airlines charge based on whichever weight is greater - the actual physical weight or the dimensional weight calculated from the package dimensions.

3. Importance of Chargeable Weight Calculation

Details: Accurate chargeable weight calculation is crucial for determining correct shipping costs, avoiding undercharges or overcharges, and ensuring proper aircraft loading and weight distribution.

4. Using the Calculator

Tips: Enter actual weight in pounds, and all dimensions (length, width, height) in inches. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why do airlines use chargeable weight?
A: Airlines use chargeable weight to account for both the physical weight and the space a shipment occupies on the aircraft, ensuring fair pricing for both dense and lightweight bulky items.

Q2: What is the 166 divisor based on?
A: The divisor 166 represents the standard dimensional factor in air freight, where 166 cubic inches is considered equivalent to 1 pound for volumetric calculations.

Q3: 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 the specific airline for their dimensional weight calculation method.

Q4: How can I reduce my chargeable weight?
A: To reduce chargeable weight, minimize package dimensions through efficient packing, use appropriately sized boxes, and reduce void space within the package.

Q5: What units should I use for international shipments?
A: For international air freight, ensure you're using the correct units as specified by the airline - typically pounds and inches for US carriers, or kilograms and centimeters for international carriers.
