Weight refers to how heavy an object is, measured in kilograms, pounds, or similar units. In shipping, actual weight is the real weight of a package as measured on a scale.

Volume, on the other hand, measures the space an object occupies, usually in cubic meters or liters. In shipping, dimensional weight is used when the size of the package impacts the shipping cost more than the actual weight. It is calculated using the formula:

This formula ensures that large but lightweight packages are charged fairly based on the space they take up in a vehicle, not just their weight. Understanding both actual and dimensional weight helps in accurately determining shipping costs.
