Determining Priority Mail Dimensional Weight

Priority Mail dimensional weight for rectangular shaped parcels to zones 58.
1. Measure the length, width, and height in inches. Round off each measurement to the nearest whole inch: (length = 21, height = 20, and width = 20).
2. Multiply length x height x width: (21 x 20 x 20) = 8,400 cubic inches.
3. If the result exceeds
1,728 cubic inches, divide the result by 194 and round up to the next whole number to determine dimensional weight in pounds:(8,400/194 = 43.29) 43.29 rounded up to the next pound is 44.
4. The rate is based on the actual weight or dimensional weight, whichever is greater.
In this example the dimensional weight for this rectangular package to zones 58 is 44 pounds.

Priority Mail dimensional weight for nonrectangular shaped parcels to zones 58.
1. Measure the length, width, and height in inches at their extreme dimensions. Round off^{1} each measurement to the nearest whole inch: (length = 30, height = 9, and width = 18).
2. Multiply length x height x width: (30 x 9 x 18) = 4,860 cubic inches.
3. Multiply the result by an adjustment factor of 0.785: 4,860 x 0.785 = 3,815.1 cubic inches.
4. If the final result exceeds 1,728 cubic inches, divide the result by 194 and round up^{2} to the next whole number to determine the dimensional weight in pounds: (3,815.1/194 = 19.66) 19.66 rounded up to the next pound is 20.
5. The rate is based on the actual weight or dimensional weight, whichever is greater.
6. If the dimensional weight exceeds 70 pounds, the package pays the 70 pound rate.
In this example the dimensional weight for this nonrectangular package to zones 58 is 20 pounds.
