Dimensional weight (volumetric weight) is calculated from package dimensions. Carriers charge the greater of actual weight or dimensional weight to prevent bulky, lightweight packages from taking up too much space.
Express carriers (DHL/UPS/FedEx) typically use ÷5000 (cm³/kg); air freight uses ÷6000; US domestic uses ÷139 (in³/lb). Always check your carrier's specific divisor.
Carriers take the greater of actual weight and dimensional weight. If your package is bulky but light, you'll pay the dimensional rate.
