How is the dimensional weight divided if it exceeds 1728 cubic inches?

The dimensional weight calculation is crucial for determining shipping costs, especially when the package is large but light for its size. When the dimensional weight exceeds 1728 cubic inches, it is divided by a specific divisor to calculate the dimensional weight.

In this case, the divisor of 166 is used when the package dimensions surpass 1728 cubic inches. This divisor helps convert the volume of the package (in cubic inches) into a weight measurement that reflects the amount of space occupied compared to its actual weight. By using 166, the resulting dimensional weight is more aligned with the actual shipping costs, reflecting the true volume of the package in relation to weight.

Understanding the use of the divisor is essential for accurate shipping and pricing, which ensures that both the USPS and the customer are aligned on the values associated with shipping services.
