Where does the ship weight and product weight number come from ?
The ship weight (ship wgt) number is calculated using Amazon's official formula (also known as the Dimensional Weight Formula). Click here to more about the formula here. The product weight comes from the amazon revenue calculator
📌 Note: Although amazon says to roundup the shipping weight, AZInsight DOES NOT do this.
Amazon formula Dimensional Weight Formula
Length x Width x Height / 139
Example: 34″ x 23″ x 23″ = 17,986 cubic inches
17,986 divided by 139 = 129.39
Remember: Even if the package only weighs 30 lbs., you will be charged for 130 lbs. based on how large the box is.
