What formula is used to calculate the net weight of a mailing?

The formula used to calculate the net weight of a mailing involves taking the gross weight and subtracting the tare weight. The gross weight represents the total weight of the mailing, including packaging, while the tare weight accounts for the weight of the packaging material itself. By subtracting the tare weight from the gross weight, you isolate the actual weight of the contents being mailed, which is referred to as the net weight. This calculation is important in mailing practices, as accurate weight measurements are crucial for determining postage and ensuring compliance with shipping regulations.
