measure cubic feet is essential for calculating shipping costs, particularly when dealing with larger items. Cubic feet is a unit of volume that measures the space an item occupies. To measure cubic feet, you need to multiply the length, width, and height of the package in inches, and then divide the result by 1,728 (the number of cubic inches in one cubic foot). Knowing the cubic feet of your package helps determine the shipping rate, especially for freight and large parcel shipments. Many carriers, such as UPS and FedEx, use dimensional weight to calculate the shipping cost for large but lightweight packages, so understanding cubic feet is important for estimating shipping expenses.
