How dim weight works
Carriers bill the greater of actual weight or dimensional weight, where dim weight = (L × W × H) / divisor. Domestic US: UPS and FedEx use 139; DHL, USPS, OnTrac use 166; Asendia uses 175. Metric carriers default to a 5,000 cm³/kg divisor. Numbers shown are pre-rounding — most carriers round up to the next whole pound or kilogram on the invoice.
