Weigh by volume, also known as volumetric weight, is a weight-measurement technique used to determine the weight of a package based on its volume.
To calculate volumetric weight, a package’s length, width, and height are multiplied to obtain its volume. This volume is then multiplied by a conversion factor, which varies based on the shipping carrier and mode of transportation. If the volumetric weight of a package exceeds its actual weight, the shipping rate is based on the volumetric weight instead. Weigh by volume is an important aspect of volume logistics, which involves managing weights and volumes to optimise efficiency in the supply chain.
