A calculation tool exists to determine the dimensional weight applied to air cargo shipments. This calculation relies on multiplying the length, width, and height of a package (in centimeters or inches) and dividing the result by a specific divisor (typically provided in kilograms or pounds). The resulting figure is compared with the actual gross weight of the shipment. The higher of the two weights is then used to calculate the shipping cost.
This practice is crucial because airlines and freight forwarders prioritize optimizing space utilization within aircraft. This methodology accounts for the density of a shipment; lighter, bulkier items may occupy more space than heavier, denser items. Historically, shipping costs were solely determined by gross weight, leading to inefficiencies and undercharging for low-density goods. Utilizing this dimensional weight ensures fair and accurate pricing reflecting the space an item occupies.
